Fig. 4From: Bias and precision of methods for estimating the difference in restricted mean survival time from an individual patient data meta-analysisDifference in restricted mean survival time estimated using the Pooled Kaplan-Meier method with random effects as a function of the time horizon t * in the MAC-NPC meta-analysis. The solid black line represents the rmstD(t *) plotted as a function of the horizon t *. The dashed horizontal line indicates the absence of a treatment effect (rmstD(t *) = 0). The grey area corresponds to the pointwise 95 % confidence interval.
