Adjusted Hazard Ratios and Corresponding 95% Confidence Intervals for Overall and Relapse-Free Survival According to Insurance Status at Time of Diagnosis

	Insurance Status at Time of Diagnosis
	Private	Medicaid/Uninsured	Medicare, <65 y	Medicare, ≥65 y
Overall survival, all-cause mortality
No. of deaths	145	50	39	225
No. at risk	547	128	81	475
Adjusted HR (95% CI) ^a	1 [reference]	1.50 (1.07–2.11)	1.69 (1.16–2.48)	1.22 (0.85–2.11)
Relapse-free survival
No. of recurrences	175	39	34	158
No. at risk	547	128	81	475
Adjusted HR (95% CI) ^a	1 [reference]	0.93 (0.65–1.35)	1.19 (0.80–1.77)	0.95 (0.65–1.77)

CI indicates confidence interval; HR, hazard ratio.

HRs and corresponding 95% CIs are adjusted for age, gender, race, smoking, alcohol consumption, tumor site, treatment, stage at diagnosis, and socioeconomic status (based on occupational prestige scores).
