Multivariable analysis of variables associated with hazard of death during long-term follow-up

	All patients		Excluding operative deaths
	HR	95% CI	HR	95% CI
Age at operation (per 10 year increase)	1.33	1.22–1.46	1.34	1.22–1.47
DLCO% (per 10-point decrement)	1.04	1.00–1.08	1.03	0.99–1.08
FEV1% (per 10-point decrement)	1.05	1.00–1.09	1.05	1.00–1.09
Performance status 0/1 vs. 2 to 4	0.69	0.56–0.85	0.72	0.57–0.90
Stage II vs. I	1.95	1.57–2.42	1.94	1.54–2.43
Stage III/IV vs. I	2.78	2.28–3.38	2.94	2.40–3.61
Creatinine (per unit increase)	1.19	1.10–1.29	1.19	1.09–1.30

CI: confidence interval; FEV1: forced expiratory capacity in the first second; DLCO: diffusing capacity of the lung for carbon monoxide.
