Parameters such as maternal age, weight, height, body mass index (BMI; calculated as weight in kilograms divided by the square of height in meters), cervical length, anterior cervical angle (ACA), Bishop score, and levator ani measurements were analyzed. Statistical significance was assessed using Fisher exact test, independent sample test, Mann\u2013Whitney\n U<\/jats:italic>\n test, or\n \u03c7<\/jats:italic>\n 2<\/jats:sup>\n test (\n P<\/jats:italic>\n \u2009<\u20090.05).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The ACA was significantly different between normal vaginal delivery (108.02\u2009\u00b1\u200922.38\u00b0) and cesarean section (86.11\u2009\u00b1\u200926.09\u00b0) groups (\n P<\/jats:italic>\n \u2009=\u20090.026). We determined an optimal ACA threshold of 96\u00b0 for the prediction of failure of progression (sensitivity: 70%, specificity: 73%). Other significant differences included maternal weight (\n P<\/jats:italic>\n \u2009=\u20090.0033), height (\n P<\/jats:italic>\n \u2009=\u20090.0033), BMI (\n P<\/jats:italic>\n \u2009=\u20090.0462), primiparity (\n P<\/jats:italic>\n \u2009=\u20090.0161), and fetal gender (\n P<\/jats:italic>\n \u2009=\u20090.0334). However, Bishop score, cervical length, and levator ani metrics showed no significant differences.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Although ACA differs significantly between vaginal delivery and cesarean section groups, its independent predictive value for induction success remains limited compared with factors like primiparity and BMI. Further prospective studies are needed to clarify its clinical utility.<\/jats:p>\n
