CI, confidence interval.
aAdjusted for: hospital/polyclinic location (urban or rural, and West or East Belarus); child’s age at the measurement of ChEAT, sex, birthweight; and mother’s age at the child’s birth, maternal and paternal education, number of older children in household and maternal smoking during pregnancy (yes or no).
