Friedman et al showed nonsignificant improvement in unadjusted analyses and we classify this study as unsuccessful; however adjustment for age, sex, baseline adherence did show significant improvement.
**
Ogedegbe et al showed nonsignificant improvement in analysis of study completers and we classify this study as unsuccessful; however, intent-to-treat analysis does predict significant improvement in intervention group adherence.
