For each predictor, r represents the simple correlation between each predictor and the outcome; β is the standardized regression coefficient after adjustment for all the other predictors;

^*p<0.05;

^**p<0.01;

^***p<0.001.

alc = frequency of maternal drinking; age = infant age since conception; sex: male=1, female=2; cig = maternal smoking (cig/day); mat. age
