note. Age, sex, and comorbidities were included a priori in each model.

^aBaseline depression score was added to the depression model and baseline anxiety score was added to the anxiety model.

^bHistory of depression was added to the depression model only and history of anxiety was added to the anxiety model only.

^cTwo patients were excluded because of failure to provide a history of psychiatric admission.

^dOne patient did not provide education history.
