Numbers in the stratified analyses may not sum up to the total due to missing values in 1st trimester BMI (n=4) and 2nd trimester glucose level (n=152)

b

Measurements of SG-adjusted BPA below the limit of detection (LOD) (16.6% of the total sample) were replaced with the LOD divided by the square root of 2
