Intracluster correlation coefficients in cluster randomized trials: empirical insights into how should they be reported
BACKGROUND Increasingly, researchers are recognizing that there are many situations where the use of a cluster randomized trial may be more appropriate than an individually randomized trial. Similarly, the need for appropriate standards of reporting of cluster trials is more widely acknowledged. METHODS In this paper, we describe the results of a survey to inform the appropriate reporting of ...

متن کاملRandomized clinical trials: how long should they last?
Well-conducted randomized clinical trials (RCT) are essential for the objective assessment of the value of new diagnostic or therapeutic medical interventions. They also will give us information about the effect of the intervention on cost and quality of life. Although the RCT was introduced 50 years ago, the requirements to ensure the best possible quality are continuously scrutinized.1–4 That...
متن کاملOn the estimation of intracluster correlation for time-to-event outcomes in cluster randomized trials.
Cluster randomized trials (CRTs) involve the random assignment of intact social units rather than independent subjects to intervention groups. Time-to-event outcomes often are endpoints in CRTs. Analyses of such data need to account for the correlation among cluster members. The intracluster correlation coefficient (ICC) is used to assess the similarity among binary and continuous outcomes that...
