Association between Induction Start Time and Labor Duration in Nulliparous Women Undergoing Elective Induction of Labor.

ABSTRACT: This study aimed to examine the association between elective induction of labor (EIOL) start time and labor duration among nulliparous women.The ARRIVE trial was a multicenter randomized controlled trial of induction of labor at 39^0/7 to 39^4/7 weeks versus expectant management in low-risk nulliparous women. In this secondary analysis, we included participants randomized to the induction group who had an EIOL without spontaneous labor or rupture of membranes prior to the induction start. The start time of EIOL was categorized as: early a.m. (midnight to 5:59 a.m.), late AM (6 AM-11:59 a.m.), early p.m. (noon-5:59 p.m.), or late p.m. (6 p.m.-11:59 p.m.). The primary outcome was labor duration. Cesarean delivery rates by induction start time were also examined. Multivari
