NICU admission and low Apgar score due to the low incidenceofbothadverseevents. Alargersamplesize is required for further study. Secondly, there were 72 cases of normal amniotic fluid volume with poor fetal outcomes. These showed that the measurement of amniotic fluid volume with SDP technique alone might not be sensitive enough to detect all the poor fetal outcomes. In order to gain more accuracy for prediction of poor fetal outcomes, multiple tests should be applied. Finally, the relative risk of SDP ≤ 2 cm with meconium stained amniotic fluid or abnormal EFM may not be the true relative risk due to each of them are confounders(13).
