Scoring system based on patients’ nutritional status and distribution of patients by sum of score
| Category | No. (%) | Score | Median PFS (95% CI) | Median OS (95% CI) |
|---|---|---|---|---|
| Anemia | ||||
| No | - | 0 | 12.6 (11.9–14.6) | 28.1 (25.6–31.5) |
| Yes | - | 1 | 10.3 (9.4–12.1) | 24.2 (21.8–26.3) |
| BMI | ||||
| 25 ≤ BMI | - | 0 | 15.6 (11.8–16.6) | 28.8 (24.9–32.8) |
| 18.5 ≤ BMI < 25 | - | 1 | 11.7 (10.6–12.7) | 25.6 (23.8–27.6) |

| 4 | 8 (1.3) | 7.0 (2.6–) | 11.2 (7.2–) |
PFS, progression free survival; CI, confidence interval; OS, overall survival; BMI, body mass index; PNI, prognostic nutritional index.
