Significant values are in bold.
Systolic blood pressure was not available for one subject. Therefore, the same size for Model 1 and Model 2 was 28. Model 1 was adjusted for maximum carotid stenosis, age, use of antihypertensive drug and systolic blood pressure; Model 2 was Model 1 plus adjustment for WMH volume.
