Association between baseline stroke and incidence of dementia in older people*
| Variable adjusted for | Number of patients with dementia (N) | Hazard ratio (95% CI) |
|---|---|---|
| *N = total number of cases plus controls with information available on the status of each vascular risk factor; ABI = atherothrombotic brain infarct; CE = cardioembolic. CI defined in glossary. | ||
| †Adjusted for age, sex, and education in addition to listed variable. | ||
| None: crude risk | 158 (1272) | 2.2 (1.5 to 3.1) |
| Age, sex, and education | 153 (1239) | 2.0 (1.4 to 2.9) |
| Apolipoprotein E ε4 genotype status† | 92 (801) | 2.8 (1.7 to 4.4) |
| Stroke type (hemisphere, ABI/CE)† | 153 (1239) | 2.0 (1.4 to 2.9) |
| Second stroke† | 153 (1239) | 2.0 (1.4 to 2.9) |
| Second stroke and stroke risk factors (hypertension, diabetes, atrial fibrillation, current smoking)† | 114 (844) | 2.4 (1.6 to 3.7) |
