AFI (antenatal assessment of amniotic fluid)
There were no cases in the NNCB group (Fig.5) in ≤ 3 and 3.5-4.5 AFI cm. Whereas, in the NCB group, we found a significant number of patients to be in these zones (***p). In AFI 5-6 cm (NCB versus NNCB) and 6.5-7.5 cm (NCB versus NNCB), there is no statistically significant difference (p = ns). We noticed the NCB group’s peak in 8-9 cm, whereas the NNCB was in the 11-12 cm zone (***p). There is a significantly higher incidence of NCB in all the zones (12.5 AFI cm onwards) than NNCB (***p). Interestingly, in the AFI 9.5-10.5 cm and 11-12 cm, the incidence of NNCB was significantly higher than NCB (***p). Overall, the graph (Fig.5) of NCB was widespread, while that of NNCB was consolidated.
