	All-cause mortality		Lung cancer mortality
Characteristic	HR	95% CI	HR	95% CI
COPD diagnosis
None	1.00	Referent	1.00	Referent
Self-reported only	0.89	(0.77–1.04)	1.09	(0.65–1.83)
CMS	1.69	(1.57–1.83)	2.28	(1.77–2.95)
CMS only	1.65	(1.50–1.80)	2.12	(1.59–2.82)

HR = Hazard Ratio; CI = Confidence Interval; Models are adjusted for coverage time on Medicare or Medicaid, sex, race, income, education, BMI, smoking, CESD-10 score and comorbidity count. A total of 862 individuals were missing covariates resulting in 26,065 individuals.
