Description of the PNI, ALI, COA-NLR, NLDA, ANPG, and HALP.

Full name	Abbreviation	Calculation formula	Cut-off value	Reference
Prognostic nutritional index	PNI	10 × albumin (g/dL) + 0.005 × absolute lymphocyte count (/μL)	48	[46]
Advanced lung cancer inflammation Index	ALI	(BMI × albumin) / NLR	18	[47]
Alb concentration combined with NLR	COA-NLR	NLR >2.5 or Alb <35 g/L, score 0; NLR >2.5 or Alb <35 g/L, score 1; NLR >2.5 and Alb <35 g/L, score 2	–	[48]
NLR × D-dimer count/Albumin	NLDA	NLR × D-dimer count/albumin	0.15	[49]
Albumin and neutrophil combined prognostic grade	ANPG	Grade 1 = elevated albumin and low neutrophil; Grade 2 = low albumin and low neutrophil, as well as elevated albumin and elevated neutrophil; Grade 3 = low albumin and elevated neutrophil.	albumin: 42.55 g/L; neutrophil: 2.895 × 109/L	[50]
Haemoglobin, albumin, lymphocyte, and platelet score	HALP	haemoglobin (g/L) × albumin (g/L) × lymphocyte (/L)/platelet (/L)	48	[51]

NLR: neutrophil-to-lymphocyte ratio; BMI: body mass index.
