Fig. 3. Multivariable logistic regression analysis of respiratory distress in neonates born to mothers infected with COVID during pregnancy (n = 199).

OR odds ratio, CI Confidence interval. Data are presented as the OR ± 95% CI; p values are calculated based on one-sided Wald’s test. Multivariable logistic regression model included maternal vaccination status and infant prematurity as predictors for respiratory distress. Unvaccinated refers to mothers who did not receive a COVID-19 vaccine compared to vaccinated mothers (reference group) who received at least 1 mRNA COVID-19 vaccine prior to infection. Preterm infants refer to neonates born at less than 37 weeks gestation compared to term infants (reference group) born at greater than or equal to 37 weeks gestation.
