From: Accurate whole-night sleep monitoring with dry-contact ear-EEG
Sleep metrics: Bland-Altman plots for four different sleep metrics, comparing manual PSG scoring and automatic earEEG scoring (leave-one-subject-out). In each plot is included the mean (full line) as well as the mean ±1.96 standard deviations. Only epochs that could be scored by the sleep technician, as well as by the algorithm (meaning it had functional electrodes in both ears) were included - the rest were marked as ‘unscored’ in both hypnograms.
