Table 4 Individual logistic regressions of maternal uterotonic administration, dilation and curettage, and magnesium sulfate in the setting of repeat cesarean birth by varying IPIs

  1. Note Adjusted for education, parity, body mass index, prenatal care, obstructed labor, induction of labor, hypertensive disease, and referral in labor; birth attendant and location of delivery were dropped from the model as physician providers are the only ones providing cesarean birth in the hospital with zero cells for non-physician providers and non-facility cesareans
  2. D&C dilation & curettage, MgSO4 magnesium sulfate
  3. aInterpregnancy interval interacted with mode of birth in the continuous IPI model, suggesting that mode of birth was modified by interpregnancy interval, p = 0.04 (AOR 0.98 [0.98.0.99], p = 0.04)
