The ROC curve for predicting perinatal outcomes according to the O/E LHR. The ROC curve for predicting mortality (A) and mortality or ECMO requirement (B) in RCDH according to O/E LHR. AUC values were 0.768 (95% CI, 0.527–1.000; P = 0.045) and 0.815 (95% CI, 0.616–1.000; P = .011), respectively. ROC, receiver operating characteristic; O/E LHR, observed-to-expected lung area-to-head circumference ratio; AUC, area under the curve; ECMO, extracorporeal membrane oxygenation; CI, confidence interval
