*Time of measurement (week 12, 25 or 33) was included as a variable in the model
^#Adjusted for the following maternal characteristics: smoking, education, parity, age and BMI before pregnancy and time of measurement (gestational week 12, 25 or 33).
^§This was computed as (10^×-1) × 100 where × is coefficient obtained from the multiple linear
analyses.
