Bilevel, bi-level positive airway pressure; BMI, body mass index; CAD, coronary artery disease; CI, confidence interval; CPAP, continuous positive airway pressure; CPET, cardiopulmonary exercise testing; ICU, intensive care unit; OR, odds ratio; ppVO2, predicted-percentage peak VO2; WHO, world health organization. Continuous data are presented as mean ± standard deviation or median (p25–p75).
