There was a significantly weak negative correlation between RI of umbilical artery Doppler and birth weight (r = \u22120.178). Additionally, a significantly weak positive correlation coefficient between CPR and birth weight (r = 0.111) was found. Length of umbilical cord coiling had a weak positive correlation with pulsatility index of uterine artery (PI-UA). RI of umbilical artery Doppler helps in predicting the small gestational age at birth with AUC: 0.72 (0.57\u20130.87).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>RI-UA and birthweight were significantly different between abnormal and normal coiling pregnancies.
