Primary and secondary maternal outcomes, categorized by severity of antepartum anemia (hemoglobin (Hb) 10.2–11g/dL and <10.2g/dL) and compared by self-identified race (Black versus non-Black)

Adjusted for age, prepregnancy body mass index, parity, and antepartum hemoglobin nadir

Multivariable modeling could not be performed for this outcome given the low number of events.
