Figure 2

The AUC when heart murmur, tachypnea, abnormal SpO2, and extracardiac malformations were used in combination to diagnose CHD. Newborns positive for heart murmur, tachypnea, and abnormal SpO2 are classified into group A. Newborns positive for murmur, tachypnea, and extracardiac malformations are classified into group B. Newborns positive for murmurs, abnormal SpO2, and extracardiac malformations are classified into group C. Newborns positive for SpO2, tachypnea, and extracardiac malformations are classified into group D. Newborns positive for four indicators are classified into group E.
