The third analysis comparing exposed individuals with and without FAS (n = 209) and individuals with ADHD who were not exposed to alcohol prenatally (as per the definition of prenatal alcohol exposure used by the authors; n = 74) led to a profile with an overall classification accuracy of 74% (95% CI: 69%–79%), with 60% (95% CI: 54%–66%) sensitivity and 76% (95% CI: 71%–81%) specificity. This evidence concerns the gene FAS and attention deficit-hyperactivity disorder.
