Mean and Standard Deviations for Brigham & Women’s Hospital Standard Population.
Table 2.
Summary Statistics of Cohort Study participants (N = 868).
Means (standard deviations) are reported for continuous variables and counts and frequencies are reported for categorical variables.
Table 3.
Cross-sectional associations between pregnancy characteristics and fetal growth measures at Observation Times 1–3.
Growth measurements are modeled both as A) Raw growth measurements, and B) Z-scored growth measurements to the Standard Population.
Table 4.
Adjusted associations between pregnancy characteristics and repeated measures of fetal growth (stacked Z-scores from observation times 1–3).
Estimates derived from linear mixed effects models to adjust for within-subject correlation of measures.

Generalized additive models (GAM) with an unstructured correlation structure between gestational age and fetal growth interacted by fetal gender (Red = Female, Black = Male) and maternal smoking status (Red = Smoking, Black = No Smoking).
