Groups/Cohorts Assigned Interventions
steroid treatment Other: sleep study
The polysomnography (PSG) (Alice 3 System; Healthdyne, Atlanta, GA) consisted of continuous polygraphic recording from surface leads for electroencephalography, electrooculography, electromyography, electrocardiography, thermistors for nasal and oral airflow, thoracic and abdominal impedance belts for respiratory effort, pulse oximeter for oxyhemoglobin level, tracheal microphone for snoring, and sensors for leg and sleep position
