NPPB and malnutrition: Patients with high NT-proBNP levels were more likely to have higher dialysis vintage, higher frequencies of weight loss, low BMI (≤23 Kg/m2), low serum albumin levels (≤38 g/L), low serum creatinine levels (≤818 μmol/L), low nPCR (≤0.8 g/kg/d), lower mean hemoglobin rate, higher frequencies of hsCRP > 5 (mg/L), nutritional supplementation, moderate malnutrition, and PEW.
