The interaction ( Figure 3 ) highlighted that OSA patients had fewer valid responses than controls in medium/long intervals, particularly 15–20 min (F (1,64) = 6.40*, p < 0.01) and 20–25 min (F (1,64) = 6.23*, p < 0.01), with a tendency towards significance also for 25–30 min (F (1,64) = 3.43, p = 0.07).
