Can’t believe nobody gives AF about this statement from Tony. How did they get the following results if the tests can’t tell if you are awake or asleep.
Something not good here.

(Preliminary results from ResApp’s study achieved 86% sensitivity and 83% specificity for identifying patients with an apnoea hypopnea index (AHI) greater than or equal to 15 (patients with moderate and severe sleep apnoea) compared with simultaneous in-laboratory polysomnography scored using the current 2012 AASM scoring criteria. The area under the receiver operating characteristic curve (a standard measure of how well a test distinguishes between two diagnostic groups, where a value of 1 represents a perfect test) was 0.91. Similar results were obtained for identifying patients with AHI greater than or equal to 30 (patients with severe sleep apnoea). These results were obtained using ten-fold cross-validation on a large cohort of 731 patients, 62% of which were male. The mean age of patients was 53 (range 18-87) with a mean AHI of 24 (range 0-196). )
