Notes from the review of this manuscript
This study reports findings for both a RCT and a quasi-experimental design (QED). In the RCT, outcomes that were not assessable at baseline received a moderate rating. Outcomes that were assessable at baseline received a low rating because the study did not establish baseline equivalence for these outcomes.
In the QED, all outcomes received a low rating because treatment and comparison groups were not enrolled in the study at the same time, creating a confounding factor.
