  Selection bias Allocation bias Confounders Data collection methods Withdrawals and dropouts Comment on the analysis
Kohen, Brooks-Gun, Leventhal, & Hertzman, 2002 S M S S NA -No power calculation
-Results unambiguously reported
-Handling of missing data not reported
-Inappropriate statistical methods: multilevel model is required to answer research question
-Risk of clustering of children within the same families
Xue, Leventhal & Brooks-Gunn et al., 2005 M M S S NA -ICC calculated
-No power calculation
-Results are unambiguously reported
-Appropriate handling of missing data
-Appropriate statistical methods with remarks:
-Analysis of level 1 and 2 variances reported
Caughy & O’Campo, 2006 M M M S NA -ICC calculated
