Comparison of ROC curves between BPV metrics ROC curves for CVD event predicted by intra-dialytic BPV (a) and visit-to-visit BPV (b). ROC curves for all-cause mortality predicted by intra-dialytic BPV (c) and visit-to-visit BPV (d). Comparison of ROC curves between intra-dialytic CV and visit-to-visit CV for CVD event (e), and for all-cause mortality (f). Comparison of ROC curves between intra-dialytic VIM and visit-to-visit VIM for CVD event (g), and for all-cause mortality (h). P value was calculated by Bootstrap test or DeLong’s test
