Low prognostic nutritional index associated with cardiovascular disease mortality in incident peritoneal dialysis patients

Purpose The prognostic nutritional index (PNI), a variable based on serum albumin concentration and total lymphocyte count in peripheral blood, is reported as a predictor of mortality in a variety of malignant tumor population. This study is aimed to evaluate whether PNI has prognostic value in patients on peritoneal dialysis (PD).
