The variables adjusted for in the multivariate model were hypertension, diabetes, metabolic syndrome, smoking, and stroke history. BPV, blood pressure variability; CI, confidence interval; CV, coefficient of variation; DBP, diastolic blood pressure; Max, maximum; Min, minimum; OR, odds ratio; SBP, systolic blood pressure; SD, standard deviation; sICH, spontaneous intracerebral hemorrhage.
