Comparison of overall survival (OS) of stage II/III gastric cancer following radical gastrectomy of the entire cohort, stratified by prognostic nutritional index (PNI) and infection (n = 2352).
| Subgroups | n (%) | Median OS (months) | Hazard Ratio (HR) | 95% Confidence Interval [CI] | P value |
|---|---|---|---|---|---|
| PNI ≥ 43.9/infection (−) | 1617 (72.3%) | 68 | Reference | Reference | |
| PNI < 43.9/infection (−) | 575 (20.7%) | 38 | 1.378 | 1.195–1.590 | <0.001 |
| PNI ≥ 43.9/infection (+) | 101 (3.7%) | 29 | 1.642 | 1.237–2.181 | 0.001 |
| PNI < 43.9/infection (+) | 59 (3.3%) | 19 | 1.755 | 1.200–2.565 | 0.004 |
(+) defined as developing post-operative infectious complications.
