Outcome	Pre-diagnostic depression			Post-diagnostic depression			Crude HR (p-value)	Adjusted HR(95% CI)	p-value
	(N = 227)			(N = 126)
	Event	Person-years	Incident rate (per1000 person-years)	Event	Person-years	Incident rate (per1000 person-years)
Death	40	1512	26·5	22	947	23·2	0·83 (0·471)	0·68 (0·40–1·14)	0·146

Adjusted HR was adjusted for Age, Gender, Hypertension, Diabetes, Hyperlipidemia, Ischemic heart disease.

HR: hazard ratio, CI: confidence interval, N: case number, %: percentage.
