Abbreviations: EDV, end-diastolic volume; ESV, end-systolic volume; IQR, interquartile range; LV, left ventricle; RV, right ventricle; SGA, small for gestational age.

^aP value as compared with controls adjusted for age, sex, asthma, educational level, smoking habit, gestational age at delivery, breastfeeding, and gestational hypertension.

^bCardiac dimensions, volumes, mass, and output were indexed for body surface area.

^cVentricular sphericity indices were calculated as base-to-apex length divided by the basal diameter.

^dRelative wall thickness was calculated as (posterior LV wall thickness × 2)/end-diastolic LV cavity diameter.
