Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in the amount of time in stage three sleep	Measured overnight polysomnography (PSG) used to identify sleep staging, reported in minutes	Baseline, approximately 30 days, and approximately 60 days
Primary	Change in sleep quality	Measured by Pittsburgh Sleep Quality Index which measures the severity of sleep disturbances. Possible scores range from 0 to 21 with higher scores indicating a worse outcome/more severe symptoms of sleep disturbance.	Baseline, approximately 30 days, and approximately 60 days
Primary	Change in self-reported sleep quality	Measured on a visual analog scale of 1-10, where 1 is not at all sleepy and 10 is as sleepy as you can imagine, how sleepy are you right now?	Baseline, approximately 30 days, and approximately 60 days
Primary	Change in sleepiness	Measured by the Stanford Sleepiness Scale that asks participate to rank their degree of sleepiness where 1 would indicate the subject currently feels least sleepy and 7 would indicate the subject feels the most sleepy.	Baseline, approximately 30 days, and approximately 60 days
Primary	Change in daytime sleepiness	Measured by Epworth Sleepiness Scale. The test is a list of eight situations in which you rate your tendency to become sleepy on a scale of 0, no chance of dozing, to 3, high chance of dozing. Total score is graded from 0-24. 0-7:It is unlikely that you are abnormally sleepy. 8-9:You have an average amount of daytime sleepiness. 10-15:You may be excessively sleepy depending on the situation. You may want to consider seeking medical attention. 16-24:You are excessively sleepy and should consider seeking medical attention.	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in blood pressure	Measured in millimeters of mercury (mmHg)	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in sympathetic nerve burst frequency	Measured by Microneurography reported as number of nerve bursts per minute (burst/min)	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in sympathetic nerve burst incidence	Measured by Microneurography reported as number of nerve burst per 100 heart beats (burst/100 heart beats)	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in sympathetic nerve burst amplitude (AU)	Measured by Microneurography reported in arbitrary units (AU)	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in total muscle sympathetic nerve activity (MSNA)	Measured by Microneurography reported burst arbitrary units per minute (AU/min)	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in arterial stiffness	Measured by applanation tonometry reported as aortic pulse wave velocity (m/sec)	Baseline, approximately 30 days, and approximately 60 days
Secondary	Change in endothelial function	Ultrasound assessment of flow-mediated vasodilation of the brachial artery. Brachial artery diameter and blood velocity will be measured after deflation to measure endothelial function.	Baseline, approximately 30 days, and approximately 60 days
