PNI [7]

PNI = 10 × albumin (g/dl) + 0.005 × total lymphocyte count (per mm³)

CONUT [84]

Serum Albumin (g/dl): ≥3.50 score 0, 3.00–3.49 score 2, 2.50–2.99 score 4, <2.50 score 6

Total lymphocyte count (mm³): ≥1600 score 0, 1200–1599 score 1, 800–1199 score 2, <800 score 3

Total cholesterol (mg/dl): ≥180 score 0, 140–179 score 1, 100–139 score 2, <100 score 3

CONUT = serum albumin score + total lymphocyte score + total cholesterol score

NRI [85]

NRI = (1.519 × serum albumin (g/dl)) + (41.7 × current weight (kg)/ideal body weight (kg))

GNRI [86]

GNRI = (1.489 × albumin (g/l)) + (41.7 × [weight/weight loss])
