Results of ordinal logit regression modeling to predict severity of coronavirus disease 2019
| Characteristic | OR | 95% CI | P value |
|---|---|---|---|
| Gestational age at PCR positivity | 0.901 | 0.846–0.957 | <.002 |
| BMI | 1.031 | 1.003–1.060 | <.04 |
| Neighborhood characteristicsa | |||
| Log of median income | 3.877 | 1.164–12.875 | <.03 |
| Log of percent less than high school | 1.987 | 1.092–3.640 | <.03 |
Under proportional odds assumption, the OR is considered uniform across 2 pairs of ordinal levels: (1) asymptomatic, (2) mild to moderate, and (3) severe to critical.
BMI, body mass index; CI, confidence interval; OR, odds ratio; PCR, polymerase chain reaction.
