Because of the role that country of origin (and intrinsically related factors) played in the misclassification of subjects and overall classification accuracies, the three analyses were repeated excluding the South African cohort. As in the main analyses, the analyses indicated that a 2-class solution fit better than a 1-class solution for the first two analyses (including (1) AE/FAS and CON and (2) AE/Non-FAS and CON). Follow up logistic regressions indicated overall classifications of 63% and 77%, respectively, both of which are statistically significant (p < .01). For the third analysis, including children with AE and ADHD, the 2-class solution did not fit the model better than a 1-class solution and no further analyses were conducted.
