Study population characteristics

Table 1 shows study population characteristic for SARS-CoV-2-exposed and unexposed mothers and their infants included in this analysis. There were group-level differences in both maternal income: F(1, 171) = 6.20, p = 0.01, and maternal education, F(1, 171) = 10.95, p = 0.001. Mothers in the unexposed group had higher socioeconomic status (income, education) than mothers in the exposed group. There were no other significant measured differences between groups. Maternal education and income are highly-correlated, r(173) = 0.64, p < 0.001. To avoid multi-collinearity, only maternal education was adjusted for in subsequent analyses.
