Figure 8.

This figure illustrates the impact of periodic leg movements (PLMs) on the sleep-disordered breathing (SDB) index in a subject in whom the RDI_NPSG was lower than the AHI1%_{ARES LAB} by 21/h. The top panel shows the signals from the nocturnal polysomnogram (NPSG), in which no SDB events are scored on the airflow channel by the technician due to the presence of clearly identifiable PLMs. The lower panel shows the Apnea Risk Evaluation System (ARES™) data collected simultaneously and the autoscored hypopnea.
