| Disease severity a | 0.64 | 0.24–1.59 | 0.34 |
| Gestational age at diagnosis of infection | 2.9 | 1.67–8.09 | 0.006 |
Abbreviation: SARS-CoV-2, severe acute respiratory syndrome coronavirus 2.

Disease severity is on a linear scale from 0 to 3.
Notes: Reference group for race/ethnicity is Asian.
Maternal age, body mass index, and gestational age at diagnosis of infection were entered into the model as continuous variables.
