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 = maternal age at delivery.
