Fig. 2: Survival curves and risk tables stratified by treatment (6x R-CHOP21 versus 6x R-CHOP21 + 2R) for patients with advanced-stage diffuse large B-cell lymphoma in the Netherlands.

Panel A shows event-free survival and panel B illustrates overall survival. The Kaplan-Meier curves and log-rank test were weighed using stabilized inverse propensity scores, but the risk tables below display the crude number of patients at risk at each time point. Stabilized inverse propensity score weights were averaged over the 50 imputations. EFS, event-free survival; OS, overall survival; HR, hazard ratio; ARD, absolute risk difference; ΔRMST, difference in restricted mean survival time; 95% CI, 95% confidence interval; -2R, 6x R-CHOP21; +2R, 6x R-CHOP21 + 2 R.
