Abbreviations: SBP: systolic blood pressure; DBP: diastolic blood pressure; CI; confidence interval; β: regression coefficient; NIHSS: National Institutes of Health Stroke Scale; LDL: low-density lipoprotein; TOAST: Trial of ORG 10172 in acute stroke treatment; NA: not available due to no event in the group. ¹Statistics were estimated using linear regression for CV of BP. Natural log transformation was applied to the CV of BP. Bold values indicate statistical significance, .
