5) the sensitivity for the composite adverse perinatal outcome varied substantially among standards (15% for NICHD to 32% for FMF) given mostly to differences in the FPR, and they subsided when the FPR was set to the same value (10%); 6) the comparison of the AUC revealed a significant improvement for the PRB/NICHD (AUC=0.70) compared to Hadlock (AUC=0.66) and FMF (AUC=0.64) standards for the prediction of perinatal mortality; complementarily, the evaluation of the partial AUC (FPR<10%) revealed that the INTERGROWTH-21 standard had an advantage over the Hadlock standard for NICU admissions and mechanical ventilation (all, p<0.05).
