Table 4.

Hazard ratios of ischemic stroke, nontraumatic intracranial hemorrhage, any hemorrhage and death compared to antiplatelet treatment

	HR for ischemic stroke (95% CI)	HR for nontraumatic intracranial hemorrhage (95% CI)	HR for any hemorrhage (95% CI)	HR for death (95% CI)
Antiplatelets	Ref.	Ref.	Ref.	Ref.
Warfarin	0.62 (0.49–0.78)***	1.16 (0.75–1.80)	1.28 (1.03–1.59)*	0.93 (0.84–1.03)
No treatment	0.80 (0.65–0.99)*	0.81 (0.51–1.28)	1.19 (0.96–1.47)	1.12 (1.02–1.23)*

Same analyses as presented in Table 3, but with antiplatelets as reference category. Adjusted for age, sex, number of drugs, Mini-Mental State Examination, dementia type (Alzheimer’s dementia versus other), nursing home placement, previous diabetes, hypertension, heart failure, ischemic stroke, any-cause hemorrhage, liver and kidney disease.
