Techniques:

(A) The correlation between the sleep duration measured via the ActiGraph and the sleep duration measured via the Ava bracelet. (B) Bland Altman plot illustrating the bias between the ActiGraph and the Ava bracelet sleep duration measurements, plotted against the ActiGraph (gold standard) sleep duration measurements.

Article Snippet: The Ava bracelet sleep duration measures had a moderate correlation to the ActiGraph ( r: 0.73), an acceptable MAPE value (<10%), and estimates that overlapped the equivalence region.

Techniques:

Equivalence testing for sleep duration. The shaded gray area indicates the proposed equivalence zone (±10% of the ActiGraph sleep duration mean). The dark bar indicates the 90% confidence interval for the mean sleep duration estimated by the Ava bracelet.
