AUC of combined indicator compared to NLR grouping and PLR grouping

Variables	Difference between areas	Standard Error	95% CI	P-value
NLR grouping vs. PLR grouping	0.047	0.038	-0.026-0.123	0.208
Combined indicator vs. PLR grouping	0.085	0.025	0.035-0.135	< 0.001
Combined indicator vs. NLR grouping	0.037	0.017	0.003-0.071	0.030

Note: NLR grouping (NLR ≤ 5.094 = 0; NLR > 5.094 = 1, NLR ≤ 5.094 as reference); PLR grouping (PLR ≤ 165.413 = 0; PLR > 165.413 = 1, PLR ≤ 165.413 as reference); Combined index: NLR + PLR. NLR, neutrophil-lymphocyte ratio; PLR, platelet-lymphocyte ratio.
