Hazard ratios for multivariate model including only covariates that make up risk score
| Covariate | Hazard ratio (95% CI) |
|---|---|
| ECOG PS 2+ | 1.65 (1.22–2.23) |
| Albumin <3.5 g/dl | 1.88 (1.38–2.58) |
| NLR >5 | 1.52 (1.13–2.04) |
| Liver metastasis | 2.44 (1.75–3.39) |
CI = confidence interval; ECOG = Eastern Cooperative Oncology Group; NLR = neutrophil to lymphocyte ratio; PS = performance status.
