Adjusted for sex, race, gestational age, maternal and paternal education, maternal intelligence quotient, and cohesion score. Least squares means (SEM) with different subscript letters within a row differ significantly at the p < .05 level. p‐values were Sidak‐adjusted to control for model‐wise type I error rates.
Bold p‐values represent those findings that are significant.
