Additional file 4: of Association between serum ferritin levels and clinical outcomes in maintenance hemodialysis patients: a retrospective single-center cohort study

Figure S3. Kaplan–Meier curves of cardiovascular events (a) and infection-related hospitalizations (b) after exclusion of patients with chronic inflammation. Black and dotted lines indicate the high-ferritin (HF) and low-ferritin (LF) groups, respectively. The HF group experienced a significantly higher number of cardiovascular events than did the LF group (log-rank test, p = 0.004). (TIF 369 kb)
