Prenatal predictors of mortality in fetuses with congenital diaphragmatic hernia: a systematic review and meta-analysis

Systematic review identifies prenatal ultrasound measurements that predict mortality in fetuses with congenital diaphragmatic hernia. Observed-to-expected lung-to-head ratio, total fetal lung volume, and lung-to-thorax ratio showed comparable predictive accuracy for neonatal outcomes, with diagnostic odds ratios exceeding 10 when below critical thresholds.
