Distribution of Epworth Sleepiness Score among OSA symptom subtypes in the Icelandic Sleep Apnea Cohort, the Sleep Apnea Global Interdisciplinary Consortium, and the Sleep Heart Health Study. The numbers in black boxes represent the mean Epworth Sleepiness Score for each subtype. In analyses that were adjusted for age, sex, BMI, and the apnea-hypopnea index, all pairwise comparisons were significant at P < .001, except for the comparison between “disturbed sleep and minimally symptomatic” in the Sleep Apnea Global Interdisciplinary Consortium, where P = .045. The yellow (Epworth Sleepiness Score = 10) and red (Epworth Sleepiness Score = 15) dashed lines represent common thresholds for denoting excessive and severely excessive daytime sleepiness, respectively.
