TURKAPNE - The Turkish Sleep Apnea Database: A National, Multicenter, Observational, Prospective Cohort Study
Primary aim of the TURKAPNE (The Turkish Sleep Apnea Database) study is to generate a
 cross-sectional nationwide database to define clinical and polysomnographic characteristics
 of the sleep apnea patients in Turkey. Associations of phenotypes of sleep apnea patients

 cardiovascular complications as well as compliance with positive airway pressure treatment
