Cesarean-rate star ratings of hospitals selected by participants who reported hospital choices A. Choice of hospital reported during pregnancy (n = 5,931 intervention, n = 6,353 controls) B. Choice of hospital reported after delivery (n = 3,703 intervention, n = 3,808 controls)

*Hospitals were assigned star ratings based on their cesarean rates, with higher star ratings assigned to hospitals with lower cesarean rates. **If participants selected hospitals without star ratings, their hospitals were treated as one-star for the purposes of analysis
