Table 2. Blood test–based parameters.

Items	Specimen	Formula
NLR	CBC	Neutrophil/Lymphocyte
PLR	CBC	Platelet/Lymphocyte
MLR	CBC	Monocyte/Lymphocyte
SII	CBC	Neutrophil × Platelet/Lymphocyte
SIRI	CBC	Neutrophil × Monocyte/Lymphocyte
HALP score	CBC, SC	Hemoglobin × Alb × Lymphocyte/Platelet
De Ritis ratio	SC	Aspartate aminotransferase/Alanine aminotransferase
GPS/mGPS	SC	GPS score
		0: CRP ≤1.0 mg/dL and Alb ≥3.5 g/dL
		1: CRP >1.0 mg/dL or Alb <3.5 g/dL
		2: CRP >1.0 mg/dL and Alb <3.5 g/dL
		Modified GPS score
		0: CRP ≤0.5 mg/dL and Alb ≥3.5 g/dL
		1: CRP >0.5 mg/dL or Alb <3.5 g/dL
		2: CRP >0.5 mg/dL and Alb <3.5 g/dL
GNRI	SC, height, BW	14.89 × Alb (g/dL) + 41.7 × BW (kg) / ideal BW (kg)
PNI	CBC, SC	10 × Alb (g/dL) + 0.005 × Lymphocyte
CONUT	SC	Alb score: 0 (3.5≤ Alb), 2 (3≤ Alb <3.5), 4 (2.5≤ Alb <3), 6 (Alb <2.5)
		TLC score: 0 (1,800≤ TLC), 1 (1,200≤ TLC <1,800, 2 (800≤ TLC <1,200), 3 (TLC <800)
		T-cho score: 0 (180≤ T-cho), 1 (140≤ T-cho <180), 2 (100≤ T-cho <140), 3 (T-cho <100)
		CONUT is the sum of Alb score, TLC score, and T-cho score
		0–1 normal, 2–4 mild, 5–8 moderate, 9–12 severe
