CV: coefficient of variation; ARV: average absolute difference between successive BP measurements; RSD: residual SD; VIM: variation independent of mean.

Data are presented as odds ratio [OR] (95% confidence intervals [95%CI]) for per 1 unit increment of systolic blood pressure [SBP] variability (i.e. for SD, the unit is 1 SD of SD; for CV, the unit is 1 SD of CV; for ARV, the unit is 1 SD of ARV; for RSD, the unit is 1 SD of RSD; and for VIM, the unit is 1 SD of VIM).

Multivariable Model: Adjusted for country, prestroke mRS score, sex, baseline NIHSS score, and history of heart disease, stroke, diabetes mellitus, or hypertension, prior antiplatelet therapy
