Table 3. Independent factors predictive of local recurrence-free survival from non-small cell lung cancer.

Factor Hazard ratio
(95% CI)		 p-value
Radiotherapy versus no radiotherapy 0.254 (0.087–0.741) .012
Negative ECE versus positive ECE 0.311 (0.118–0.799) .016
Chemotherapy versus no chemotherapy 0.900 (0.372–2.177) .815
Age at diagnosis 0.988 (0.941–1.038) .642
Female versus male 0.883 (0.364–2.139) .782

p-values were derived from the Cox proportional-hazards model, with simultaneous inclusion of all factors shown. Abbreviations: CI, confidence interval; ECE, extracapsular extension.
