BMI = body mass index; COPD = chronic obstructive pulmonary disease; EDS =excessive daytime sleepiness; ESS = Epworth sleepiness scale;

^*Class 1= high priority for further testing (PSG); Non-class 1= lower priority for further testing (PSG)

^**Number and (%) of participants that answered, “yes” on the Somni-Sage® questionnaire

EDS was considered positive if a driver had an Epworth Sleepiness Scale (ESS) ≥10 and/or answered “often” to the following question: “Do you become drowsy while driving?”
