Methods To Reduce the Impact of Intraclass Correlation in Group-Randomized Trials.
Murray, David M.; Blitstein, Jonathan L.
Evaluation Review, v27 n1 p79-103 Feb 2002
Studied two methods to reduce the impact of intraclass correlation (ICC) in group-randomized trials (GRTs) : modeling time and regression adjustment for covariates. Findings for 1,188 ICC estimates from 17 articles (21 studies) confirm that both methods can improve the efficiency of analyses shown to be valid across conditions in GRTs. (SLD)
