Epoch-by-epoch sleep-wake classification agreement between  Basis B1  and PSG and actigraphy and PSG.
Figure Legend Snippet: Epoch-by-epoch sleep-wake classification agreement between Basis B1 and PSG and actigraphy and PSG.

Techniques Used:

Accuracy, sensitivity, and specificity percentages for  Basis B1  measurements of LS, DS, and RS compared with PSG.

Techniques Used:

Correlation matrix demonstrating correspondence of  Basis B1,  ACT-auto, and ACT-human assessment of sleep variables with PSG assessment of the same sleep variables.
Figure Legend Snippet: Correlation matrix demonstrating correspondence of Basis B1, ACT-auto, and ACT-human assessment of sleep variables with PSG assessment of the same sleep variables.

Techniques Used:

Sleep variable means across devices; sleep variable mean differences for  Basis B1  vs PSG, ACT-auto vs PSG, and ACT-human vs PSG derived from Bland Altman; and a comparison of mean differences across devices.

Techniques Used: Derivative Assay, Comparison

Mean bias of the differences between Basis B1 and PSG outcomes are demonstrated by a solid black line, and lower and upper agreement limits (mean difference ± 1.96 SD) are demonstrated by dotted lines for each Bland-Altman plot. PSG = polysomnography, SE = sleep efficiency, SOL = sleep onset latency, TST = total sleep time, TST-DS = duration of deep sleep, TST-LS = duration of light sleep, TST-S = duration of REM sleep, WASO = wake after sleep onset.

Article Snippet: While commercially available systems such as the Zephyr BioPatch (Zephyr Technology, Anapolis, MD) and the Basis B1 Watch (Basis Science, Inc., San Francisco, CA) monitor heart rate and body acceleration, they could potentially miss these subtler physiological responses that are captured by the SCG and pressure sensor.
