Fig. 4: Stratified analysis of overall survival according to the risk group based on the International Prognostic Index.

From: Comparative effectiveness of 6x R-CHOP21 versus 6x R-CHOP21 + 2 R for patients with advanced-stage diffuse large B-cell lymphoma

Fig. 4

The graphs show (A) event rates using Kaplan-Meier curves weighted with stabilized inverse propensity scores and risk tables below display the crude number of patients at risk at each time point, (B) hazard ratios with a p-value resulting from testing the interaction between IPI risk and treatment regimen, (C) absolute risk differences (ARD), and (D) differences in restricted mean survival time (ΔRMST) for 6x R-CHOP21 and 6x R-CHOP21 + 2 R for OS. Overall results are depicted by the horizontal dotted line; 6x R-CHOP21 + 2 R showed effectiveness in preventing all-cause deaths. IPI scores and stabilized inverse propensity score weights were averaged over the 50 imputations. N, sample size; OS, overall survival; ARD, absolute risk difference, ΔRMST, difference in restricted mean survival time; IPI, International Prognostic Index.
