Results of the competing regression analysis to verify the independent association of Eurolung aggregate score with 3-year disease-specific survival (competing risk: death from other cancers or death from noncancer causes)
| Variables | Cause-specific HR | SE | P value | 95% CI |
|---|---|---|---|---|
| Eurolung class | ||||
| Class A (no. 702) | Reference | |||
| Class B (no. 446) | 1.4 | 0.3 | .08 | 0.95-2.2 |
| Class C (no. 113) | 2.4 | 0.6 | .001 | 1.4-4.0 |
| Class D (no. 98) | 1.6 | 0.5 | .15 | 0.9-2.9 |
| PS >1 | 1.6 | 0.4 | .049 | 1.0-2.6 |
| pT >1 | 1.8 | 0.4 | .004 | 1.2-2.6 |
| pN positive | 2.7 | 0.5 | <.0001 | 1.9-4.0 |
Eurolung levels have been fitted as separate covariates. Only independent predictors with P < .1 are displayed. Other variables used in the regression analysis: coronary artery disease, cerebrovascular disease, chronic kidney disease, diabetes, ppoDLCO.
HR, Hazard ratio; SE, standard error; CI, confidence interval; PS, performance score.
