A Comparison of Prediction of Adverse Perinatal Outcomes between Hadlock and INTERGROWTH-21^st Standards at the Third Trimester

Table 3

Comparison of predictive values for adverse perinatal outcomes between the INTERGROWTH and Hadlock EFWc.

Variable	Cutoff value (percentile)^∗	Sensitivity (95% CI)	Specificity (95% CI)	Positive predictive value (95% CI)	Negative predictive value (95% CI)
INTERGROWTH-EFWc	11.61	87.9 (72.0-97.0)	80.5 (77.5-83.5)	18.5 (15.5-21.4)	99.2 (98.6-99.9)
Hadlock-EFWc	8.65	93.9 (80.0-99.0)	81.2 (78.3-84.3)	20.1 (17.1-23.2)	99.6 (99.2-100)

who has a percentile of EFWc of < the cutoff value was judged to develop at least one adverse perinatal outcome.
