Discriminant power of models with GPS, mGPS, CRP, albumin and CRP/albumin ratio with regard to one-year mortality in the overall population (n = 1604 for all models).

Model	Harrell’s C [95% CI]	NRI+ [95% CI]	NRI− [95% CI]
Baseline model: age, sex, tumor site, metastatic status, ECOG-PS, G8	0.82 [0.80; 0.83]	-	-
Baseline model + GPS	0.84 [0.82; 0.85]	0.10 [0.02; 0.16]	0.01 [−0.02; 0.09]
Baseline model + mGPS	0.83 [0.82; 0.85]	0.08 [−0.03; 0.14]	0.01 [−0.03; 0.09]
Baseline model + CRP	0.83 [0.82; 0.85]	0.11 [−0.01; 0.15]	−0.01 [−0.05; 0.09]
Baseline model + albumin	0.83 [0.81; 0.85]	0.07 [−0.04; 0.13]	0.00 [−0.04; 0.09]
Baseline model + CRP/albumin ratio	0.83 [0.82; 0.85]	0.14 [0.02; 0.17]	−0.01 [−0.05; 0.08]

ECOG-PS: Eastern Cooperative Oncology Group performance status; CRP: C-reactive protein; GPS: Glasgow Prognostic Score; mGPS: modified Glasgow Prognostic Score; NRI: net reclassification improvement; CI: confidence interval.
