Do these Subject Areas make sense for this article? The interpretation of the sleep duration question may also affect the level of agreement between the methods. Our algorithm was validated against data from a polysomnography study on 28 persons which found a longer time window and lower angle threshold to have better sensitivity to wakefulness, while the reverse was true for sensitivity to sleep.
However, no differences in agreement as a function of these variables were observed for total sleep duration. Polysomnography Is the Subject Area «Polysomnography» applicable to this article?
