Supplemental Table 2. Multivariate-adjusted hazard ratios for stroke incidence according to age category and sex.

Variables	60–74 years (n = 1502)			≥ 75 years (n = 563)
	Men (n = 648) HR (95% CI)	Women (n = 854) HR (95% CI)	P value for interaction	Men (n = 192) HR (95% CI)	Women (n = 371) HR (95% CI)	P value for interaction
Age (per 1 standard deviation)	1.43 (0.96–2.12)	1.56 (1.03–2.35)	0.64	1.29 (0.77–2.17)	1.24 (0.84–1.81)	0.83
Hypertension	2.25 (1.37–3.69)	1.97 (1.23–3.16)	0.72	1.78 (0.90–3.50)	1.47 (0.91–2.39)	0.63
Diabetes mellitus	1.52 (0.88–2.60)	1.54 (0.83–2.83)	0.96	0.21 (0.03–1.52)	0.89 (0.41–1.94)	0.2
Heart disease	1.29 (0.69–2.43)	1.47 (0.74–2.94)	0.9	1.25 (0.54–2.87)	0.86 (0.42–1.76)	0.55
Current drinker	1.37 (0.81–2.30)	1.46 (0.77–2.76)	0.96	1.06 (0.56–1.98)	0.85 (0.39–1.83)	0.63
Junior high school	1.04 (0.58–1.88)	7.06 (1.82–27.48)	0.012	1.18 (0.42–3.32)	1.61 (0.50–5.22)	0.72

Hazard ratios (HRs) given with 95% confidence intervals (CIs) were adjusted for all other variables shown in the table. Age per 1 standard deviation corresponded to 7.6 years. P denotes the significance of interaction between sex and each variable.
