  1. Significant group differences highlighted in bold. *Noncategorical data were not normally distributed; therefore, Kruskal–Wallis test was conducted (median and IQR values reported). aTest statistic for multiple-group comparison; Chi-square, ANOVA, or Kruskal–Wallis tests performed. Where test statistic is not reported, there were less than five expected values in cells, and Fisher’s exact test was performed. bGender information not available for two participants from AS group. cData derived from Wessex Behavior Scale. dData derived from Background Information Questionnaire
