Comparison of stroke and cardiovascular event rates in patients with stroke/TIA at 3 months and 1 year with high and low systolic or diastolic blood pressure variability. (A) Stroke recurrence rate in patients with stroke/TIA at 3 months in different BPV groups. (B) Cardiovascular event rate in patients with stroke/TIA at 3 months in different BPV groups. (C) Stroke recurrence rate in patients with stroke/TIA at 1 year in different BPV groups. (D) Cardiovascular event rate in patients with stroke/TIA at 1 year in different BPV groups. BPV, blood pressure variability; CV, coefficient of variation; DBP, diastolic blood pressure; SBP, systolic blood pressure; STD, standard deviation; TIA, transient ischaemic attack.

HR for cardiovascular events and stroke recurrence within 3 months according to the quartiles of SBP variability and DBP variability. Adjusted for age, gender, body mass index, medical history (hypertension, diabetes mellitus and dyslipidaemia), qualifying event, and concomitant medication (antiplatelet, antilipid and antihypertension) and mean systolic blood pressure in 3 months. CV, coefficient of variation; DBP, diastolic blood pressure; SBP, systolic blood pressure; STD, standard deviation.

Adjusted for age, gender, body mass index, medical history (hypertension, diabetes mellitus and dyslipidaemia), qualifying event, and concomitant medication (antiplatelet, antilipid and antihypertension) and mean systolic blood pressure in 3 months. CV, coefficient of variation; DBP, diastolic blood pressure; SBP, systolic blood pressure; STD, standard deviation.
