Fig. 3From: Impact of red cell distribution width and red cell distribution width/albumin ratio on all-cause mortality in patients with type 2 diabetes and foot ulcers: a retrospective cohort studyROC curves of RDW and RDW/ALB ratio for predicting the all-cause mortality in the overall study population. The optimal cut-off values of RDW and RDW/ALB ratio for the all-cause mortality were 14.3% and 0.3809%/(g/L), respectively. The AUC of RDW was 0.634, 95% CI: 0.601–0.666; the AUC of RDW/ALB ratio was 0.660, 95% CI: 0.628–0.692.
