  • Ref, reference category. —, not applicable.

  • a n = 24 (7.7%) were excluded from analysis because of missing data on preterm birth.

  • b n = 6 (4.9%) were excluded from analysis because of missing data on preterm birth.

  • c Each cutoff-specific RR was adjusted for the other variables in the model. The RRs shown for child sex, payer source, and gestational age were derived from the model that used an ACE risk cutoff of ≥2.

  • ** P < .05;

  • *** P < .01.
