From: Validation of Oura ring energy expenditure and steps in laboratory and free-living
Comparison of free-living Oura- and accelerometer-derived energy expenditure metrics, and Oura- and pedometer-derived step metrics illustrated in Bland-Altman plots. Points depict the Oura and accelerometer or pedometer values for each day of data within the free-living setting. Dashed lines depict mean difference and dotted lines limits of agreement (±1.96 SD).
