We are looking for a difference in cesarean rates between the experimental arm and the maintenance arm. Evaluating the data as an equivalence study (no difference between the interventions) would significantly increase the sample size needed for the study. With our current sample size calculation, if a cesarean rate difference is not found between the groups (meaning discontinuation of oxytocin is not inferior to the maintenance use of oxytocin in active labor), we can state that our data do not support a significant increase (60% increase) in the risk of cesarean delivery rate when reducing the amount of oxytocin used for induction of labor.
