The regression coefficient was statistically significant, . Adjusted for serum albumin, hs-CRP, ALP, sFerr, and creatinine. Alb: predialysis serum albumin; hs-CRP: predialysis serum high-sensitivity C-reactive protein; ALP: predialysis serum alkaline phosphatase; sFerr: predialysis serum ferritin; creatinine: predialysis serum creatinine.
