FIG. 2.

Scatter plots and fitted lines showing three-way interactions: Age, Premutation status, and Potentially Confounding Comorbid Diagnoses Codes on FXTAS Rating Scale Total score. The fitted lines are drawn from data points, illustrating the bivariate associations between age and the total FXTAS Rating Scale. For each fitted line, the unstandardized regression coefficient (simple slope), the standard error of the coefficient (in parenthesis) and the p-value are presented. (A) Participants who did not have potentially confounding comorbid codes. (B) Participants who had any potentially confounding comorbid codes.
