Practice-based Opportunities for Weight Reduction Trials
funded by the National Heart, Lung, and Blood Institute
The National Heart, Lung, and Blood Institute (NHLBI) funded three effectiveness trials of weight loss interventions in primary care settings. Unlike traditional multi-center clinical trials, each study was conducted as an independent trial at a separate institution with a distinct protocol. Efforts were made to coordinate and standardize several aspects of the trials. The three trials formed a collaborative group, the Practice-based Opportunities for Weight Reduction (POWER) Trials Collaborative Research Group.
