Epoch-by-epoch sleep-wake classification agreement between Basis B1 and PSG and actigraphy and PSG.

Global Sleep/Wake Assessment	Basis B1 vs PSG	ACT-auto vs PSG	ACT-human vs PSG
Global accuracy (AUC; % ± SD)	54.2 ± 8.2%	63.7 ± 12.8%	65.8 ± 15.1%
Global sensitivity (% ± SD)	98.9 ± 2.7%	98.6 ± 1.1%	98.6 ± 1.2%
Global specificity (% ± SD)	8.1 ± 15.0%	30.1 ± 26.1%	29.8 ± 26.8%

Accuracy is represented by AUC; sensitivity is the ability to detect true sleep compared with PSG; and specificity is the ability to detect true wake compared with PSG. ACT-auto = actigraphy automatically scored by the software program, ACT-human = human-adjusted actigraphy scoring, AUC = area under the curve, PSG = polysomnography.
