Relationship between level of blood pressure (BP) and grade of white matter hyperintensities: the EVA MRI cohort*
| BP at baseline, mm Hg | Grade of white matter hyperintensities | ||
|---|---|---|---|
| Mild (n = 319) reference group | Moderate (n = 373) OR (95% CI) | Severe (n = 138) OR (95% CI) | |
| * Polytomous logistic regression adjusting for age, sex, and antihypertensive medication at entry. | |||
| SBP = systolic BP; DBP = diastolic BP. | |||
| SBP <140 and DBP <90 | 1.0 | 1.0 | 1.0 |
| SBP 140–160 or DBP 90–95 | 1.0 | 0.8 (0.6–1.3) | 1.5 (0.9–2.3) |
| SBP ≥160 or DBP ≥95 | 1.0 | 1.3 (0.8–2.3) | 2.9 (1.6–5.3) |
