Parity
We noted that the highest incidence of NCB was found in primigravida, whereas the highest incidence of NNCB was seen in the 2nd gravida (Fig.4). When we compared the various NCB groups, there was a statistically significant difference in all four groups (primigravida, 2nd gravida, 3rd gravida, and 4th gravida). We found that as parity increases, the incidence of NCB decreases (***p).
