Data presented as mean ± SD or number (percentage). BMI = body mass index, ECOG = Eastern Cooperative Oncology Group, ESS = Epworth Sleepiness Scale, ODI = oxygen desaturation index, PKY = packs per year, SpO2 = oxygen saturation, Tsat90% = percentage of sleep time with oxygen saturation < 90%, Tsat90 mins = total sleep time (minutes) with oxygen saturation < 90%.
