Multivariate analyses for overall survival of patients with MSS
| Factor | P | Exp (B) | 95% CI min | 95% CI max |
|---|---|---|---|---|
| Primary tumor(yes vs. no) | 0.050 | 0.33 | 0.10 | 1.00 |
| Ascites(yes vs. no) | < 0.001 | 0.20 | 0.08 | 0.49 |
| Line of immunotherapy (I–II vs. III–IV) | 0.004 | 0.24 | 0.09 | 0.63 |
| NLR (< 1.8 vs. ≥ 1.8) | 0.006 | 0.23 | 0.08 | 0.65 |
MSS: microsatellite stable; NLR: neutrophil-lymphocyte ratio
