Comparing the CD because of arrest labor with old recommendations (group 1) and new recommendations (group 2): The CD rate decreased significantly from 7.33% to 3.22% (OR=0.41, p=0.001), the CD rate for nulliparous decreased from 16.9% to 6.36% (OR=0.33, p <0.001), the CD rate for multiparous decreased from 3.59% to 1.61% (OR=0.43, p <0.05), and maternal - neonatal outcomes did not differ between the two groups.
