Results from Zero-inflated or Poisson models adjusted for: age at delivery, parity, education, race, and marital status. Standard error in parentheses; *p < .05, **p < .01, ***p < .001;! Poisson models. b = coefficient estimate; se = standard error; ED = emergency department; IP = inpatient; ICU = intensive care unit; OP = outpatient; b = coefficient estimate; se = standard error.
