* Adjusted for maternal age, maternal body mass index, smoking status, income status, race, parity, birth year, pre-pregnancy hypertension, pre-pregnancy diabetes, and co-medication use during pregnancy. CCS: Corticosteroids; HCQ: hydroxychloroquine; SSZ: sulfasalazine. Bold values denote statistical significance at the p < 0.05 level.
