RICCO

The RICCO project (Reporting Intraclass Correlation Coefficients as Outcomes in cluster randomized trials) has for aim to change the paradigm about the use of intraclass correlation coefficient (ICC). The objective is to study the ICC in different cluster randomized trials (different kinds of intervention, different kinds of clusters, different kinds of study end points,…) and to see how an intervention can impact the ICC. This is a project that calls for the sharing of databases of already analyzed trials within the network. The principal investigator is Bruno Giraudeau of the CIC-P 1415 (Tours).
