Mean systolic and diastolic blood pressure, prevalence of hypertension, and pulse pressure by absence or presence of small vessel disease in patients with Alzheimer’s disease*
| Age at MRI | Small vessel disease | ||
|---|---|---|---|
| Absent (n = 36) | Present (n = 116) | ||
| *Values are age and sex adjusted means (SD) or percentages. Differences between those with or without small vessel disease were tested by age and sex adjusted analysis of covariance. | |||
