Author (Year) | Was the study described as randomized, a randomized trial, a randomized clinical trial, or an RCT? | Was the method of randomization adequate (i.e., use of randomly generated assignment)? | Was the treatment allocation concealed (so that assignments could not be predicted)? | Were study participants and providers blinded to treatment group assignment? | Were the people assessing the outcomes blinded to the participants' group assignments? | Were the groups similar at baseline on important characteristics that could affect outcomes (e.g., demographics, risk factors, co-morbid conditions)? | Was the overall drop-out rate from the study at endpoint 20% or lower of the number allocated to treatment? | Was the differential drop-out rate (between treatment groups) at endpoint 15 percentage points or lower? | Was there high adherence to the intervention protocols for each treatment group? | Were other interventions avoided or similar in the groups (e.g., similar background treatments)? | Were outcomes assessed using valid and reliable measures, implemented consistently across all study participants? | Did the authors report that the sample size was sufficiently large to be able to detect a difference in the main outcome between groups with at least 80% power? | Were outcomes reported or subgroups analyzed prespecified (i.e., identified before analyses were conducted)? | Were all randomized participants analyzed in the group to which they were originally assigned, i.e., did they use an intention-to-treat analysis? | Quality Rating |
