A receiver operating characteristic curve for the number of days for which oligohydramnios persisted in relation to the onset of neonatal BPD. The cut-off value was calculated by using Youden’s index. Sixteen cases who were diagnosed with clinical CAM during pregnancy were excluded from a total of 73 cases. Analysis was performed for the remaining 57 cases. AUC was 0.956 (95% CI: 0.902-1.000). The cut-off value for the duration of oligohydramnios as a risk factor for BPD was four days. In this case, the levels of sensitivity and specificity in predicting the onset of neonatal BPD were 0.941 and 0.917 respectively
