Bland-Altman plots for the predictions of our model compared to the total sleep duration measured by the Polar Vantage and Oura ring.

Bland-Altman plots for the predictions of our model compared to the total sleep duration measured by the Polar Vantage and Oura ring.

<p>(A) No systematic distortion is visible for the Polar Vantage. (B) The estimates of our model seem to overestimate the Oura ring’s total sleep duration the longer the sleep/TiB is.</p> <p>(PNG)</p>
