  1. Model adjusted for variables including maternal age, parity, gestational age, mode of delivery, GDM/DM, PROM, histological CAM, NRFS, birth weight and infant sex. Neonates born to mothers without ACS treatment were used as a reference in both groups. SGA, small for gestational age; HDP, hypertensive disorders of pregnancy; ACS, antenatal corticosteroids; aOR, adjusted odds ratio; Short-term composite adverse outcomes: in-hospital death, intraventricular haemorrhage (grade III or IV) and periventricular leukomalacia, Long-term composite adverse outcomes: death after NICU discharge, cerebral palsy and developmental quotient <70. Bold indicates a significant association. P-value for interaction <0.05 indicates a significant difference in the effect of ACS treatment between the two groups.
