Figure 1. Age in years was studied for both the groups NCB and NNCB. Age ≤ 24 yrs (NCB v/s NNCB) and 25 – 29 yrs (NCB v/s NNCB) were significant ***p < 0.0001. However, for the age group 30 - 34 yrs and ≥ 35 yrs (NCB v/s NNCB), there was no significance (p = ns) (One-way Anova analysis).
Figure 2. The NCB and the NNCB groups were compared for the socio-economic status (SES). The NCB incidence declined as SES was progressed towards the higher side, while simultaneously, the incidence of the NNCB increased***p < 0.0001 (Tukey’s comparison test).
Figure 3. The level of significance (***p < 0.0001) was obtained when compared between NCB and NNCB for the education levels (Tukey’s comparison test). High school (NCB v/s NNCB) was not significant (ns), whereas intermediate and graduates (NCB v/s NNCB) were significant ***p < 0.0001.
Figure 4. The parity was investigated (Primigravida, 2nd gravida, 3rd gravida, 4th gravida) in both NCB and NNCB. The level of significance for Primi (NCB v/s NNCB) was ***p < 0.0001, 2nd gravida (NCB v/s NNCB) was **p < 0.001, and that of 3rd and 4th gravida (NCB v/s NNCB) was *p < 0.05 (Tukey’s multiple comparison test).Figure 5. AFI in cm was compared for NCB and NNCB groups. There was a significant difference in both groups***p < 0.0001. There is a widespread graph in NCB compared to consolidated graph of NNCB, suggesting the occurrence of nuchal cord in both excessive and reduced liquor. The peak of NCB falls at AFI of 8 to 9 cm, whereas, that of NNCB falls at AFI 11 to 12 cm. There were no cases below 5 cm in NNCB, whereas there are significant number of cases in NCB from AFI 14 cm onwards. Generalised shift of the graph to the left is seen in NCB group compared to NNCB group.
Figure 6 .   Intrapartum liquor amount for NCB and NNCB groups is plotted. We observed a significant difference in all groups (***p < 0.0001) through a One-way Anova analysis. The presence of nuchal cord is associated with both excessive and reduced – absent liquor. The adequate liquor is significantly higher in NNCB compared to reduced – absent liquor in NNCB (***p < 0.0001).Figure 7.  1 min APGAR score < 7 was assessed for NCB v/s NNCB. The significant difference ***p < 0.0001 was observed. Similarly, 1 min APGAR score ≤ 7 shows the significance of **p < 0.001. NCB is significantly associated with 1 min APGAR score < 7.
Figure 8. The requirement for O2 (> 30 min) and NICU was studied in NCB and NNCB groups. The level of significance measured with One-way Anova in need for O2 (NCB v/s NNCB) was ***p < 0.0001, in need for NICU (NCB v/s NNCB) was *p < 0.05, and for Healthy group (NCB v/s NNCB) was **p < 0.001.

Figure 10. The fetal gender in NCB and NNCB groups is compared. The male gender is significantly associated with NCB group (***p < 0.0001).
Figure 11. The fetal birth weight in both NCB and NNCB groups is compared. The peak of the graph of NCB falls at 2.61 to 2.8 kg, whereas, that of the NNCB falls at 2.81 to 3 kg. There is significant higher number of cases of low birth weight in NCB group compared to NNCB group (***p < 0.0001).
