we used clinical judgment and chose the traditional variables from each measure. Although the effect sizes for these variables were mostly in the large range, the inclusion of additional or different variables may have improved our classification accuracy. In the previous study, we included 22 variables, while there were only 11 included in the current study. We selected a smaller number of variables in order to achieve a more parsimonious neuropsychological variable list, which would be more feasible for a clinical setting. Even given the increased heterogeneity and reduced number of variables, the classification accuracy of both FAS and non-FAS subjects with AE was highly statistically significant.
