For those surrogate outcomes , low-strength evidence failed to show difference .
In subgroup analysis , high strength evidence supported a lower BP with HBPT that lasted for 6 or 12 months and was accompanied with counselling support from study personnel .
HBPT can improve BP control in the hypertensive patients .
It may be more efficacious when a proactive additional support is provided during the intervention process
To summarise evidence about the effectiveness of home blood pressure telemonitoring ( HBPT )  and identify the key components of intervention .
Efficacy of a weight-loss website based on positive deviance. A randomized trial.
BACKGROUND Web-based interventions for weight control could promote more-widespread dissemination of weight-loss opportunities ; however , they remain limited in effectiveness . Incorporating weight-control practice s used by individuals with long-term weight-loss success ( " positive deviants " ) may improve the efficacy of web-based weight control interventions . PURPOSE To evaluate the efficacy of AchieveTogether , a web-based weight-loss intervention for adults based on user-generated weight-loss strategies from successful weight losers . DESIGN In 2009 - 2010 , participants were r and omized to either a 12-week  web-based intervention , AchieveTogether , or a wait-list control condition . SETTING / PARTICIPANTS 100 overweight or obese adults participated in the study . INTERVENTION AchieveTogether was design ed to help individuals implement weight control practice s used by others who successfully lost and maintained weight . MAIN OUTCOME MEASURES The primary outcome was change in weight . Secondary outcomes included blood pressure , daily caloric intake , quality of life , and use of weight control practice s. ANCOVA , with adjustment for baseline values on outcome measures , was used to assess differences between groups in primary and secondary outcomes . Statistical analyses were conducted in 2010 - 2011 . RESULTS Most participants were women ( 69.7 % ) and white ( 90.8 % ) , with a mean age of 50.3 years and baseline BMI of 33.2 ; 88 % completed post-program assessment s.  Mean weight loss among intervention participants was -1.4 kg ( 95 % CI= -2.2 , -0.5 ) , compared with a mean weight gain of 0.6 kg ( 95 % CI= -0.3 , 1.4 ) in control participants ( p<0.01 ) . CONCLUSIONS User-generated weight-loss practice s from " positive deviants " could promote weight control in web-based interventions ; however , further research is needed to improve program efficacy .
