Table 5 Definition of a simple protein-energy wasting score

From: Recent advances in the pathophysiology and management of protein-energy wasting in chronic kidney disease

Serum albumin (g/dL) ≤3.8
Body mass index (kg/m2) ≤23
SCr/BSA (μmol/L/m2) ≤380
nPNA (g/kg/day) ≤0.8
  1. nPNA normalized protein nitrogen appearance, Scr/BSA predialysis serum creatinine/body surface area (using postdialysis body weight)
