There were significant differences between the mean (SD) age of the patients (45.6 (7.8)) and the controls (34.0 (10.1)), F = 211, p< 0.0001. Nevertheless, there was no correlation between age and CTQ score in the patients (r = 0.07, p = 0.211) or the controls (r = 0.09, p = 0.276). Inclusion of age as a covariate had no effect on outcomes.
