Quantile g-computation estimates of adjusted mean differences (ψ) in MSEL Composite scores and T-scores of subscales of children at 6, 12, 24, and 36 months of age in association with a simultaneous one-tertile increase in prenatal maternal urinary concentrations of six OPE biomarkers detected in ≥60% of samples.
