  • Bold indicates significant p values.

  • *Analysis is based on an ANCOVA model for change from baseline in the adherence to continuous positive airway pressure (CPAP) treatment variables as response and with treatment group as a factor along with baseline adherence to CPAP treatment variables as covariates.

  • †LS mean: least square mean for the change from baseline in the adherence to CPAP treatment variables in the ANCOVA model.

  • ANCOVA, analysis of covariance; BMI, body mass index; ESS, Epworth Sleepiness Scale; EQ, EuroQol; FOSQ, Functional Outcomes of Sleep Questionnaire; Quebec, Quebec Sleep Questionnaire; QoL, quality of life; VAS, visual analogue scale.
