Gestational age represented the time Echocardiography was measured. Follow-up SBP and DBP were defined as the highest blood pressure collected during the follow-up.

Values are given as mean ± standard deviation, median (interquartile range) or count (percentage).

BMI body mass index, BSA body surface area, SBP systolic blood pressure, DBP diastolic blood pressure.
