Fig. 3From: Risk prediction in multicentre studies when there is confounding by cluster or informative cluster sizeInformative Cluster size (ICS). Comparison of Basic models (‘Basic’) and models adjusting for the cluster size (‘N’) fitted by three Methods. ICC = 0.2. Performance measures from top left to bottom right: Calibration Intercept, Calibration slope, RPMSE and C-statistic. Conditional (left Panel) and Marginal (right panel) predictions are shownBack to article page
