Design outcomes

Primary

Measure	Time frame
The prevalance of sleep apnea syndrome in fatigue patients. The diagnosis of sleep apnea syndrome is made by portable oxgen saturation monitor.The diagnostic criteria for sleep apnea syndrome is as follows;The number of the event that their oxgen saturation levels are below 3% or less than their baseline saturation levels are 15 times or more in an hour(positive likelihood ratio 5.1,negative likelihood ratio 0.54 to the diagnosis of sleep apnea syndrome by polysomnography). The prevalance of sleep apnea syndrome is defined as the number of included patient diagnosed as sleep apnea syndrome devided by the number of patient those who visited office for the first time with complaint of persistent fatigue .	—
