Values are presented as means ± SD or number (%).

SBP, systolic blood pressure; DBP, diastolic blood pressure.

^aTachycardia was defined as a heart rate of > 100 beats per minute.

^bSevere hypertension was defined as a systolic blood pressure of ≥ 180 mmHg or a diastolic blood pressure of ≥ 120 mmHg.
