Association of serum hepcidin-25 levels with all-cause mortality in PD patients using restricted cubic spline. Baseline serum hepcidin-25 levels were modeled as a continuous variable, and the model was unadjusted (A) and multivariate (B) adjusted (adjusted for age, gender, body mass index, uric acid, corrected calcium, phosphorus, albumin, comorbidity score, hemoglobin, residual renal function, total Kt/V, high-sensitivity C-reactive protein level, serum ferritin and treatment of erythropoiesis-stimulating agents (ESAs) and/or iron). HR, hazard ratio.
