Continuous variables reported as mean ± SD if normally distributed, or median (first, third quartile) if skewed. Categorical variable reported as total number (n). Test statistics, degrees of freedom, and associated p-values are reported for between-group differences using: one-way ANOVA (F), Kruskal-Wallis test (H), or Chi Square test (χ2), where appropriate. P-value significance levels: *p < 0.05, **p < 0.01, ***p < 0.001.
SRI, (fetal exposure to) serotonin reuptake inhibitor antidepressant; g, grams; cm, centimeters.
