Multivariate analysis of OS in NSCLC patients
| OS | |||
|---|---|---|---|
| Characteristic | P | HR | 95% CI |
| Age (≤ 60, > 60 years) | 0.001 * | 1.672 | 1.349–2.071 |
| Tumor length (≤ 4, > 4) | 0.217 | 1.155 | 0.919–1.451 |
| T stage (T1/T2, T3/T4) | 0.326 | 1.139 | 0.878–1.479 |
| Lymph node metastasis (negative, positive) | 0.026 * | 1.401 | 1.041–1.885 |
| TNM stage (I/II, III) | 0.001 * | 1.850 | 1.410–2.428 |
| Operation duration (minutes) (≤ 150, > 150) |
0.340 | 1.109 | 0.897–1.372 |
| Intraoperative blood loss (mL) (≤ 150, > 150) | 0.039 * | 1.291 | 1.085–1.667 |
| SII (< 419.6, ≥ 419.6) | 0.034 * | 1.256 | 1.018–1.551 |
| NLR (< 1.74, ≥ 1.74) | 0.119 | 1.202 | 0.954–1.515 |
| PLR (< 87.83, ≥ 87.83) | 0.092 | 1.247 | 0.965–1.613 |
*
P < 0.05 is considered significant. CI, confidence interval; HR, hazard ratio; NLR, neutrophil‐lymphocyte ratio; NSCLC, non‐small‐cell lung cancer; OS, overall survival; PLR, platelet‐lymphocyte ratio; SII, systemic immune‐inflammation index; TNM, tumor node metastasis.
