Mortality Hazard Ratios (With 95% CI and p Values) of Lung Cancer-Specific Survival and Nonlung Cancer Competing Causes of Death, by the Presence or Absence of Lung Cancer Resection

	Adjusted Hazard Ratios (95% CI) of Cause-Specific Death by Resected vs. Unresected; p Value
Cause of Death	Stage IA	Stages IB-IIIA
[n]	[1260]	[2646]
Death from lung cancer	0.38 (0.28–0.52), p < 0.001	0.37 (0.32–0.42), p < 0.001
Death from other causes	1.73 (1.07–1.78), p = 0.02	1.18 (0.86–1.63), p = 0.31

Note: Separate analyses were performed for all stages and for individual disease stages at the time of diagnosis. Each analysis was adjusted for age, sex, race, education, smoking status, stage (except for stage IA), and study sites.
