Abbreviations used: RR = risk ratio.
Data are presented as proportion of n and risk ratio (95% confidence interval).
Some risk ratios are not calculable due to sparse data.
Adjusted model controlled for maternal age, race, parity, body mass index, prior cesarean, cervical ripening (yes/no), labor induction, and payor
All maternal outcomes defined as diagnosed clinically and documented in the medical record
Composite measure consisting of fetal or neonatal death; intubation, continuous positive airway pressure or high-flow nasal cannula for ventilation or cardiorespiratory support within the first 72 hours of life; Apgar score at five minutes of less than four; neonatal encephalopathy; seizures; sepsis; meconium aspiration syndrome; birth trauma [bone fractures, brachial plexus palsy, other neurologic injury, retinal hemorrhage, facial nerve injury]; intracranial or subgaleal hemorrhage; or hypotension requiring pressor support
