Table 2.

Incidence and risk of brain infarcts by sex

Overall (n=2612) Men (n=1070) Women (n=1542) Men vs. Women
Infarct region Incidence, n (%) Incidence, n (%) Incidence, n (%) Model 1
Risk-ratio (95%CI)		 Model 2
Risk-ratio (95%CI)
Overall 545 (20.9) 283 (26.4) 262 (17.0) 1.8 (1.5–2.3) 1.5 (1.1–1.9)
Cortical 203 (7.8) 126 (11.8) 77 (5.0) 2.9 (2.1–4.0) 2.4 (1.6–3.7)
Cerebellar 340 (13.0) 162 (15.1) 178 (11.5) 1.3 (1.0–1.7) 1.0 (0.7–1.5)
Subcortical 116 (4.4) 68 (6.4) 48 (3.1) 2.3 (1.6–3.4) 1.9 (1.0–3.4)

Values in first three columns are number and percent of incident brain infarcts, overall and by sex. Values in last two columns are risk-ratios with 95% confidence intervals (95%CI). Model 1: Adjusted for age and time interval between MR scans. Model 2: Additionally adjusted for brain volume and vascular risk-factors.
