Alcohol and infant malformation Data from a prospective study of maternal drinking and congenital malformations (Agresti, 1996). After the first three months of pregnancy, the women in the sample completed a questionnaire about alcohol consumption. Following childbirth, observations were recorded on the presence or absence of congenital sex organ malformations. A chi-square was used to determine significant difference in the congenital sex organ malformations. Below are the data using SPSS.
