Note: Data are presented as numbers (% of total inclusion number) or median (IQR), bold type p values indicate statistical significance differences between the groups. US1, ultrasound scan ≤24 weeks gestational age (GA); US2, ultrasound scan 24–30 weeks GA; US3 ultrasound scan ≥30 weeks GA. Prenatal liver position “up”: liver intrathoracic. CDH severity: combination of O/E LHR and liver position according to Jani et al. 16 : mild (O/E LHR > 46% or O/E LHR 36%–45% + liver down), moderate (O/E LHR 36%–45% + liver up or O/E LHR 26%–35%), severe (O/E LHR ≤ 25%).
Abbreviation: BMI, body mass index; IQR, interquartile range; PH, pulmonary hypertension.
