Abstract: Twenty-one studies (772 participants) were included in this review with two additional 2012 studies identified as 'awaiting classification'. Physical training was well tolerated with no adverse effects reported. None of the studies mentioned worsening of asthma symptoms following physical training. Physical training showed marked improvement in cardiopulmonary fitness as measured by a statistically and clinically significant increase in maximum oxygen uptake (mean difference (MD) 4.92 mL/kg/min; 95% confidence interval (CI) 3.98 to 5.87; P < 0.00001; 8 studies on 267 participants); however, no statistically significant effects were observed for forced expiratory volume in 1 second (FEV1), forced vital capacity (FVC), minute ventilation at maximal exercise (VEmax) or peak expiratory flow rate (PEFR). Meta-analysis of four studies detected a statistically significant increase in maximum heart rate, and following a sensitivity analysis and removal of two studies significance was maintained (MD 3.67 bpm; 95% CI 0.90 to 3.44; P = 0.01). Although there were insufficient data to pool results due to diverse reporting tools, there was some evidence to suggest that physical training may have positive effects on health-related quality of life, with four of five studies producing a statistically and clinically significant benefit. This review demonstrated that physical training showed significant improvement in maximum oxygen uptake, though no effects were observed in other measures of pulmonary function. Physical training was well tolerated among people with asthma in the included studies and, as such, people with stable asthma should be encouraged to participate in regular exercise training, without fear of symptom exacerbation. More research is needed to understand the mechanisms by which physical activity impacts asthma management.

Plain-language summary: The review of trials found that exercise training (including running, gymnastics, cycling, swimming, weights and walking) was well tolerated among the study participants. This review also found that physical training improved cardiopulmonary fitness and showed some positive effects for health-related quality of life. However, physical training had no significant effect on resting lung function. In summary, people with stable asthma should be encouraged to participate in regular exercise training that is within their capacity without fear of worsening of their asthma symptoms.
Abstract: Two studies involving 1002 participants compared personal assistance versus usual care. Whilst personal assistance was generally preferred over other services, some people prefer other services. Personal assistance may have some benefits for some recipients and may benefit caregivers. Paid assistance probably substitutes for informal care and may cost government more than alternatives; however, some evidence suggests it may reduce costs. The total costs to recipients and society are unknown. Research in this field is limited. Personal assistance is expensive and difficult to organise, especially in places that do not already have services in place, but its total cost relative to other services is unknown. When implementing new programmes, recipients could be randomly assigned to different forms of assistance (e.g. organised by individual users versus organised through a cooperative). While advocates may support personal assistance for myriad reasons, this review demonstrates that further studies are required to determine which models of assistance are most effective and efficient for particular people.

Plain-language summary: This review investigated the effectiveness of personal assistance versus any other form of care for adults with both physical and intellectual impairments. A literature search identified 2 studies that met the inclusion criteria, which included 1002 participants. They suggested that personal assistance may be preferred over other services; however, some people prefer other models of care. This review indicates that personal assistance may have some benefits for some recipients and their informal caregivers. Paid assistance might substitute for informal care and cost government more than alternative arrangements; however, the relative total costs to recipients and society are unknown.
Abstract: New searches in 2013 did not identify any relevant new studies. All six included studies used a single dose of triptan to treat an attack of moderate to severe pain intensity. Subcutaneous sumatriptan was given to 131 participants at a 6 mg dose, and 88 at a 12 mg dose. Oral or intranasal zolmitriptan was given to 231 participants at a 5 mg dose, and 223 at a 10 mg dose. Placebo was given to 326 participants. Triptans were more effective than placebo for headache relief and pain-free responses. By 15 minutes after treatment with subcutaneous sumatriptan 6 mg, 48% of participants were pain-free and 75% had no pain or mild pain (17% and 32% respectively with placebo). NNTs for subcutaneous sumatriptan 6 mg were 3.3 (95% CI 2.4 to 5.0) and 2.4 (1.9 to 3.2) respectively. Intranasal zolmitriptan 10 mg was of less benefit, with 12% of participants pain-free and 28% with no or mild pain (3% and 7% respectively with placebo). NNTs for intranasal zolmitriptan 10 mg were 11 (6.4 to 49) and 4.9 (3.3 to 9.2) respectively. Based on limited data, subcutaneous sumatriptan 6 mg was superior to intranasal zolmitriptan 5 mg or 10 mg for rapid (15 minute) responses, which are important in this condition. Oral routes of administration are not appropriate.

Plain-language summary: The review found six studies examining two different triptans. The number of people in the studies was limited. Within 15 minutes of using subcutaneous sumatriptan 6 mg, almost 8 in 10 participants had no worse than mild pain, and 5 in 10 were pain-free. Within 15 minutes of using intranasal zolmitriptan 5 mg, about 3 in 10 had no worse than mild pain, and 1 in 10 was pain-free. Adverse events were more common with a triptan than with placebo but they were generally of mild to moderate severity. Cluster headache is an awful thing to have. More research on how to get better pain relief faster, and to more patients, would be welcome.
Abstract: Three trials met eligibility criteria. A 16-week behaviour therapy intervention was used in two trials, and a 12-week cognitive-behaviour therapy intervention in the third. Duration of follow-up varied, ranging from 0 to 12 months.  Two trials (total 166 participants) provided data comparing combination with psychotherapy alone (both using behaviour therapy). No statistically significant differences were observed in response during the intervention (relative risk (RR) for combination 1.25, 95% CI 0.78 to 2.03, P = 0.35), at the end of the intervention (RR 0.78, 0.45 to 1.35, P = 0.37), or at the last follow-up time point, although the follow-up data suggested that the combination might be inferior to behaviour therapy alone (RR 0.62, 0.36 to 1.07, P = 0.08).  One trial (77 participants) compared combination with a benzodiazepine alone. No differences were found in response during the intervention (RR 1.57, 0.83 to 2.98, P = 0.17). Although the combination appeared to be superior to the benzodiazepine alone at the end of treatment (RR 3.39, 1.03 to 11.21, P = 0.05) the finding was only borderline statistically significant, and no significant differences were observed at the 7-month follow-up (RR 2.31, 0.79 to 6.74, P = 0.12). The review established the paucity of high quality evidence investigating the efficacy of psychotherapy combined with benzodiazepines for panic disorder. Currently, there is inadequate evidence to assess the clinical effects of psychotherapy combined with benzodiazepines for patients who are diagnosed with panic disorder.

Plain-language summary: This review included randomised controlled trials comparing the combination of psychotherapy and a benzodiazepine with either the psychotherapy or the benzodiazapine alone for people with panic disorder. We were able to include only three trials in this review. Two could be used in the comparison of the combination of psychotherapy and benzodiazepine versus psychotherapy alone and one in the comparison of the combination with benzodiazepine. These comparisons involved just 166 patients and 77 patients, respectively. These small numbers make it difficult to detect any differences between combination treatments and either treatment alone. The trials which compared the combination of treatments with psychotherapy alone (both using behaviour therapy) indicated no differences in response between the two approaches, either during the intervention, at the end of the intervention, or at the last follow-up time point. The trial which compared the combination of treatments with a benzodiazepine alone demonstrated no differences in response during the intervention. Although the combination of treatments appeared to be more effective than the benzodiazepine alone at the end of treatment, no significant differences were observed at the 7-month follow-up. Before evidence-based treatment recommendations are possible, more randomised controlled trials are required, comparing the combination of psychotherapy and benzodiazepines with either treatment alone, and involving enough people to be able to detect a true difference between the treatments if one exists.
Abstract: Seven trials were included with a total of 426 children studied (274 with oral prednisone vs. placebo, 106 with intravenous steroids vs placebo and 46 with nebulised budesonide vs prednisolone). A significant number of steroid treated children were discharged early after admission (>4 hours) with an OR of 7.00 (95% CI: 2.98 to 16.45) and NNT of 3 (95%CI: 2 to 8). The length of stay was shorter in the steroid groups with a WMD of -8.75 hours (95% CI: -19.23 to 1.74). There were no significant differences between groups in pulmonary function or oxygen saturation measurements. Children treated with steroids in hospital were less likely to relapse within one to three months with OR 0.19 (95%CI: 0.07 to 0.55) and NNT of 3 (95%CI: 2 to 7). The single small study that compared nebulised budesonide to oral prednisone failed to demonstrate equivalence or a difference between each therapy. Systemic corticosteroids produce some improvements for children admitted to hospital with acute asthma. The benefits may include earlier discharge and fewer relapses. Inhaled or nebulised corticosteroids cannot be recommended as equivalent to systemic steroids at this time. Further studies examining differing doses and routes of administration for corticosteroids will clarify the optimal therapy.

Plain-language summary: This review asked the question "do steroid drugs help children admitted to hospital with asthma?" We found that steroids given by mouth or through an intravenous tube help children recover from acute asthma. The benefits may include earlier discharge or a shorter stay in hospital. Children were less likely to come back to hospital in the one to three months following the admission. However, the evidence was not overwhelming due to the limited number of studies available and different medicines used. Further research needs to concentrate on the best medications to use and the best route of administration.
Abstract: We included two RCTs conducted in Taiwan with a total of 131 participants. We did not perform a meta-analysis as the trials were assessing different outcomes. Neither trial met our pre-defined primary outcome criteria of myopia progression defined as one diopter mean change. Only one trial reported the changes of axial length without non-significant difference among groups and both trials reported that several children experienced mild pain during acupuncture stimulation. Two trials are included in this review but no conclusions can be drawn for the benefit of co-acupressure for slowing progress of myopia in children. Further evidence in the form of RCTs are needed before any recommendations can be made for the use of acupuncture treatment in clinical use. These trials should compare acupuncture to placebo and have large sample sizes. Other types of acupuncture (such as auricular acupuncture) should be explored further as well as compliance with treatment for at least six months or longer. Axial length elongation of the eye should be investigated for at least one year. The potential to reduce/eliminate pain from acupuncture experienced by children should also be reviewed.

Plain-language summary: This review aimed to assess the effectiveness and safety of acupuncture in slowing the progression of myopia in children and adolescents. We included two studies conducted in Taiwan with a total of 131 school children and did not combine the results as the two trials assessed different outcomes. One study found no significant difference in changes in the length of the eyes. Both studies found several children experienced mild pain while pressing and dropped out. The included studies in this review were unable to provide evidence of the effect of acupuncture for slowing the progression of myopia. More trials should be conducted where acupuncture is compared to placebo, other types of acupuncture are investigated, compliance with treatment for at least six months is explored and axial length elongation of the eye should be for at least one year.
Abstract: Fourteen unique trials with 1497 randomised participants were included. Antifungal prophylaxis did not reduce mortality (RR 0.90, 95% CI 0.57 to 1.44). In liver transplant recipients, a significant reduction in IFIs was demonstrated for fluconazole (RR 0.28, 95% CI 0.13 to 0.57). Although less data were available for itraconazole and liposomal amphotericin B, indirect comparisons and one direct comparative trial suggested similar efficacy. Fluconazole prophylaxis did not significantly increase invasive infections or colonisation with fluconazole-resistant fungi. In renal and cardiac transplant recipients, neither ketoconazole nor clotrimazole significantly reduced invasive infections. Overall, the strength and precision of comparisons however were limited by a paucity of data. For liver transplant recipients, antifungal prophylaxis with fluconazole significantly reduces the incidence of IFIs with no definite mortality benefit. Given a 10% incidence of IFI, 14 liver transplant recipients would require fluconazole prophylaxis to prevent one infection. In transplant centres where the incidence of IFIs is high, or in situations where the individual risk is great, antifungal prophylaxis should be considered.

Plain-language summary: This review found that fluconazole, used as a preventive drug, significantly reduced the number of invasive fungal infections in liver transplant patients. More studies are needed to determine how effective antifungal drugs are for pancreas, heart, kidney and lung transplant patients.
Abstract: Only two trials of limited quality met our inclusion criteria. One study compared two biphasic pills and one triphasic pill, each containing levonorgestrel and ethinyl estradiol. No important differences emerged, and the frequency of discontinuation due to medical problems was similar with all three pills. The other trial compared a biphasic pill containing norethindrone (Ortho 10/11) with a triphasic pill containing levonorgestrel (Triphasil) and with another triphasic containing norethindrone (Ortho 7/7/7). The biphasic pill had inferior cycle control compared with the levonorgestrel triphasic. The odds ratio of cycles with intermenstrual bleeding was 1.70 (95% confidence interval (CI) 1.29 to 2.24) for the biphasic compared with the triphasic levonorgestrel pill. The odds ratio of cycles without withdrawal bleeding was 6.48 (95% CI 3.13 to 13.39). In contrast, cycle control with the biphasic pill was comparable to that of the triphasic containing the same progestin (norethindrone). The available evidence is limited and the internal validity of these trials is questionable. Given the high losses to follow up, these reports may even be considered observational. Given that caveat, the biphasic pill containing norethindrone was associated with inferior cycle control compared with the triphasic pill containing levonorgestrel. The choice of progestin may be more important than the phasic regimen in determining bleeding patterns.

Plain-language summary: We did a computer search for studies of birth control pills with two phases versus pills with three phases. We also wrote to researchers and manufacturers to find other trials. We included randomized trials in any language. We found only two trials that looked at two-phase versus three-phase birth control pills. The studies did not have good methods and the authors did not report all their methods. Many women dropped out of the studies, which affects what can be said about the results. One study compared two types of two-phase pills with a three-phase pill. The pills did not differ in any major ways, including the numbers of women who stopped using the pills due to health problems. The other trial compared a two-phase pill with two different three-phase pills. The two-phase pill had worse bleeding patterns than the three-phase pill with a different hormone (levonorgestrel). In contrast, bleeding with the two-phase pill was like that of the three-phase pill with the same hormone (norethindrone). The type of hormone may be more important than the phases for cycle control. These trials did not provide enough evidence to say if three-phase pills worked any better than two-phase types for birth control, bleeding patterns, or staying on the pill. More research would be needed to show whether three-phase pills were better than two-phase pills. However, two-phase pills are not used enough to justify further research.
Abstract: The search yielded 39 studies. We included five studies in the review with a total of 884 participants. We excluded 31 studies and designated three as awaiting assessment. The data from the included studies provide some evidence that hydroxyzine is more effective than placebo for GAD (odds ratio (OR) 0.30, 95% CI 0.15 to 0.58) and that it is also acceptable/tolerable (OR 1.00, 95% CI 0.63 to 1.58) (OR 1.49, 95% CI 0.92 to 2.40). Compared to other anxiolytic agents (benzodiazepines and buspirone), hydroxyzine was equivalent in terms of efficacy, acceptability and tolerability (hydroxyzine vs chloridiazepoxide: OR 0.75, 95% CI 0.35 to 1.62; hydroxyzine vs buspirone efficacy OR 0.76, 95% CI 0.40 to 1.42). In terms of side effects, hydroxyzine was associated with a higher rate of sleepiness/drowsiness than the active comparators (OR 1.74, 95% CI 0.86 to 3.53). There was, however, a high risk of bias in the included studies. The included studies did not report on all the outcomes that were pre-specified in the protocol for this review. Even though more effective than placebo, due to the high risk of bias of the included studies, the small number of studies and the overall small sample size, it is not possible to recommend hydroxyzine as a reliable first-line treatment in GAD.

Plain-language summary: This review shows that hydroxyzine is better than placebo in terms of anxiety symptoms in individuals with generalised anxiety disorder (GAD). Too few data were available to be able to draw any conclusions about the efficacy and tolerability of hydroxyzine compared with benzodiazepines and buspirone. Given the robust evidence for the efficacy of antidepressants for GAD, these findings suggest that hydroxyzine should not be recommended as first-line treatment GAD.
Abstract: 21 randomized controlled trials (RCTs) in 1,993 patients with primary hypertension met the inclusion criteria for this review - ACEIs (5 trials), CCBs (7 trials), ARBs (6 trials), diuretics (2 trials), alpha-blockers (1 trial), and beta-blockers (1 trial). Meta-analysis showed significant heterogeneity across trials. No RCT reported on all cause mortality, cardiovascular mortality, cardiovascular morbidity and serious adverse events. There was no statistically significant difference for overall adverse events (RR=0.78, 95%CI: 0.37 to 1.65) and withdrawals due to adverse events (RR=0.53, 95%CI: 0.26 to 1.07). No significant differences were noted for morning SBP (-1.62 mm Hg, 95% CI: -4.19 to 0.95) and morning DBP (-1.21 mm Hg, 95% CI: -3.28 to 0.86); but 24-hour BP (SBP: -1.71 mm Hg, 95% CI: -2.78 to -0.65; DBP: -1.38 mm Hg, 95% CI: -2.13 to -0.62) showed a statistically significant difference. No RCT reported on clinically relevant outcome measures - all cause mortality, cardiovascular morbidity and morbidity. There were no significant differences in overall adverse events and withdrawals due to adverse events among the evening versus morning dosing regimens. In terms of BP lowering efficacy, for 24-hour SBP and DBP, the data suggests that better blood pressure control was achieved with bedtime dosing than morning administration of antihypertensive medication, the clinical significance of which is not known.

Plain-language summary: This review examined the administration-time-related effects of once-daily evening versus morning regimen on death, cardiovascular outcomes and blood pressure reduction. The interventions included chronotherapeutic delivery formulations and conventional antihypertensive agents. 21 trials, involving 1,993 patients with primary hypertension were identified. We concluded that evening dosing with antihypertensive drugs had a slightly better blood pressure control than the morning dosing regimen in 24-hour BP, but its effect on death and adverse cardiovascular outcomes is not known.
Abstract: We included 16 trials involving 2648 participants. We were able to analyse 15 of the trials with 2496 participants. The pooled analysis of all the trials showed that there was no significant difference in the incidence of clinical failure on about days 10 to 14 between the two groups (risk ratio (RR), random-effects 1.09; 95% confidence interval (CI) 0.64 to 1.85). A subgroup analysis in trials with acute bronchitis participants showed significantly lower clinical failure in the azithromycin group compared to amoxycillin or amoxyclav (RR random-effects 0.63; 95% CI 0.45 to 0.88). A sensitivity analysis showed a non-significant reduction in clinical failure in azithromycin-treated participants (RR 0.55; 95% CI 0.25 to 1.21) in three adequately concealed studies, compared to RR 1.32; 95% CI 0.70 to 2.49 in 12 studies with inadequate concealment. Twelve trials reported the incidence of microbial eradication and there was no significant difference between the two groups (RR 0.95; 95% CI 0.87 to 1.03). The reduction of adverse events in the azithromycin group was RR 0.76 (95% CI 0.57 to 1.00). There is unclear evidence that azithromycin is superior to amoxycillin or amoxyclav in treating acute LRTI. In patients with acute bronchitis of a suspected bacterial cause, azithromycin tends to be more effective in terms of lower incidence of treatment failure and adverse events than amoxycillin or amoxyclav. However, most studies were of unclear methodological quality and had small sample sizes; future trials of high methodological quality and adequate sizes are needed.

Plain-language summary: Randomised controlled trials (RCTs) and quasi-RCTs, comparing azithromycin to amoxycillin or amoxycillin/clavulanic acid in participants with clinical evidence of an acute LRTI, such as acute bronchitis, pneumonia and acute exacerbation of chronic bronchitis. We analysed the results from 15 trials with 2496 participants. The effects of azithromycin on cure, improvement or failure were not better than those of amoxycillin or amoxyclav. However, azithromycin seems to have a lower incidence of adverse events than amoxycillin or amoxyclav but it is not significant. Overall the quality of the evidence for the main outcome is low as only three of 15 included trials showed adequate allocation concealment. Hence, currently, there is insufficient evidence to show conclusively that azithromycin is superior to amoxycillin or amoxyclav in treating acute LRTI.
