There were 35 AE/Non-FAS subjects that were misclassified as CON. In comparison to the AE subjects that were correctly classified (n = 82), these subjects differed significantly on FSIQ (higher), country (fewer from South Africa than U.S.), race (more White subjects), ethnicity (more Hispanic subjects), growth deficiency (less likely), weight (less likely to be ≤10th percentile), microcephaly (less likely), and thin vermillion (less likely). They did not differ on age, sex, handedness, ethnicity, height, structural abnormality, short palpebral fissures, smooth philtrum, or presence of an ADHD diagnosis. They differed significantly on all of the neuropsychological variables (misclassified > correctly classified).
