Raw means and standard deviations for demographic and sleep factors for 3 profiles in the clinic and community samples, respectively.

None of these demographic and sleep variables were different between the 3 samples, and only SaO2 moderated by premorbid IQ for the clinic and no. of comorbidities for the community sample explained group membership. Depression, anxiety, and stress were measured on the Depression Anxiety, and Stress Scale-21. All scores on these subscales fell in the normal range of symptomatology. Only individuals in the strong and inattentive fast thinkers of the sleep clinic population fell over the normal range with scores ≥ 10. AHI = apnea-hypopnea index, BMI = body mass index, ESS = Epworth Sleepiness Scale, SpO2 = saturation over sleep study period.
