	IPI as continuous variable	IPI as dichotomous variable (< 12 vs $\geq$ 12 months)	IPI as dichotomous variable (< 18 vs $\geq$ 18 months)	IPI as dichotomous variable (< 24 vs $\geq$ 24 months)

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
