Unadjusted and adjusted mortality and rehospitalization^*

	Unadjusted		Adjusted
Clinical Outcome	Not Living Alone HR (Referent)	Living Alone HR (95% CI)	Not Living Alone HR (Referent)	Living Alone HR (95% CI)	p-value
1-Year mortality	1.00	1.49 (1.02, 2.18)	1.00	0.95 (0.52, 1.74)	0.869
4-Year mortality	1.00	1.56 (1.24, 1.96)	1.00	1.35 (0.94, 1.93)	0.107
1-Year readmission	1.00	1.02 (0.86, 1.22)	1.00	0.99 (0.76, 1.28)	0.919

Abbreviations: CI, confidence interval; HR, hazard ratio.

Cox-proportional hazards regression was used to calculate adjusted mortality and readmission. Hazard ratios were adjusted for patient demographics (age, gender, race, body mass index, marital status, employment status, living location, pet ownership, medical care payer, usual source of care, financial barriers to health care utilization), medical history (hypertension, depression, previous MI, CHF), clinical presentation and treatment (left ventricular systolic function, creatinine, receipt of ACE inhibitor and beta blockers at discharge), ESSI score, and baseline health status scores.
