1
Model adjusted for: age, insurance status, education, body mass index, income, and gestational age at assessment.
2
Ordinal logistic regression within multiple imputation was used for nonbinary outcome (Quartile 4 = reference).
3
N in adjusted model = 7,956 with imputation for missing covariates.
4
The outcome was analyzed by quartile (Q) from the highest or best (Q4, reference) to the lowest or worst dietary quality (Q1).
∗
Statistically significant finding with P-value < 0.05.
