Factor	AUC	95% confidence interval	p-value
GPS	0.847	0.66–1.00	<0.01
NLR	0.665	0.51–0.82	0.04
PI	0.708	0.51–0.90	0.04
PLR	0.605	0.40–0.81	0.32
PNI	0.829	0.65–1.00	<0.01
SII	0.683	0.53–0.84	0.02
AGR	0.810	0.66–0.96	<0.01

AUC, area under the receiver operating characteristic curve; GPS, Glasgow prognostic score; NLR, neutrophil-to-lymphocyte ratio; PI, prognostic index; PLR, platelet-to-lymphocyte ratio; PNI, prognostic nutritional index; SII, systemic immune-inflammation index; AGR, albumin-to-globulin ratio.
