Figure 5.

Bland-Altman agreement for scalp-EEG vs in-ear EEG.

Notes: (A) Bland-Altman agreement for individual naps (in-ear EEG minus scalp-EEG), usual night sleep visit (left) and sleep restriction visit (right). Dashed lines show the CI. (B) Bland-Altman agreement for all naps combined (in-ear EEG minus scalp-EEG), sleep restriction (orange) and usual night sleep (purple). Dashed orange lines are the CI for sleep restriction, whereas dashed purple lines show the CI for usual night sleep. Note that several data points are overlapped.

Abbreviation: EEG, electroencephalogram.
