Fig. 2From: Intra-dialytic blood pressure variability is a greater predictor of cardiovascular events in hemodialysis patientsComparison of covariates and outcomes between high and low CV groups HD patients were divided into two groups based on intra-dialytic CV (a–c) and visit-to-visit CV (d–f). (a, d) Boxplot of CV, SBP, Hb and Alb. P value was calculated by Wilcoxon rank sum test. (b, e) Kaplan-Meier survival plots of CVD morbidity. (c, f) Kaplan-Meier survival plots of all-cause mortality. P value was calculated by log-rank testBack to article page
