At the class level , behavioural therapy ( alone or in combination with stimulants ) , stimulants , and non-stimulant seemed significantly more efficacious than placebo .
Behavioural therapy in combination with stimulants seemed superior to stimulants or non-stimulants .
Stimulants seemed superior to behavioural therapy , cognitive training and non-stimulants .
Behavioural therapy , stimulants and their combination showed the best profile of acceptability .
Stimulants and non-stimulants seemed well tolerated .
Among medications , methylpheni date , amphetamine , atomoxetine , guanfacine and clonidine seemed significantly more efficacious than placebo .
Methylpheni date and amphetamine seemed more efficacious than atomoxetine and guanfacine .
Methylpheni date and clonidine seemed better accepted than placebo and atomoxetine .
Most of the efficacious pharmacological treatments were associated with harms ( anorexia , weight loss and insomnia ) , but an increased risk of serious adverse events was not observed .
There is lack of evidence for cognitive training , neurofeedback , antidepressants , antipsychotics , dietary therapy , fatty acids , and other complementary and alternative medicine .
Clinical differences may exist between the pharmacological and non-pharmacological treatment used for the management of ADHD .
BACKGROUND Attention deficit hyperactivity disorder ( ADHD ) is one of the most commonly diagnosed psychiatric disorders in childhood .
A wide variety of treatments have been used for the management of ADHD .
We aim ed to compare the efficacy and safety of pharmacological , psychological and complementary and alternative medicine interventions for the treatment of ADHD in children and adolescents .
Increasing value and reducing waste in research design, conduct, and analysis
Correctable weaknesses in the design , conduct , and analysis of biomedical and public health research studies can produce misleading results and waste valuable re sources . Small effects can be difficult to distinguish from bias introduced by study design and analyses . An absence of detailed written protocol s and poor documentation of research is common . Information obtained might not be useful or important , and statistical precision or power is often too low or used in a misleading way . Insufficient consideration might be given to both previous and continuing studies . Arbitrary choice of analyses and an overemphasis on r and om extremes might affect the reported findings . Several problems relate to the research workforce , including failure to involve experienced statisticians and method ologists , failure to train clinical research ers and laboratory scientists in research methods and design , and the involvement of stakeholders with conflicts of interest . Inadequate emphasis is placed on recording of research decisions and on reproducibility of research . Finally , reward systems incentivise quantity more than quality , and novelty more than reliability . We propose potential solutions for these problems , including improvements in protocol s and documentation , consideration of evidence from studies in progress , st and ardisation of research efforts , optimisation and training of an experienced and non-conflicted scientific workforce , and reconsideration of scientific reward systems
