Figure 2 Bland-Altman plots of respiratory rates and heartbeat rates between ECG and radar for individual users and multiusers. The bias (solid line) and 95% limits of agreement (dashed lines) are indicated, as well as confidence intervals around the LOA (error bars). Data from each subject are indicated using a unique marker (open circle). (A, B) The measurements of RR of individual users and multiusers subgroups. (C, D) The measurements of HR of individual users and multiusers subgroups. All analyses were performed using MedCalc Statistical Software (Version 20.100, Belgium). RR – respiratory rates; HR – heartbeat rates; ECG – electrocardiogram; LOA – limits of agreement.
