Responders among the combined populations with obstructive sleep apnea in the studies based on changes from baseline in Functional Outcomes of Sleep Questionnaire (FOSQ) Total Score. Participants were considered to be “responders” to modafinil treatment if their Total score increased by ≥ 2 points and each individual domain score by ≥ 1 point. Those whose Total score did not change by ≥ 2 points and did not worsen compared with baseline were considered to be “stable.” “Nonresponders” were those without a ≥ 2-point change in Total score and a decrease in each individual domain score.
