Figure 4 (A–D) Bland-Altman plots of RR and heartbeat rates HR between ECG and Radar for the male and female subgroups of multiuser groups. The bias (solid line) and 95% LOA (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). All analyses were performed using MedCalc Statistical Software (Version 20.100, Belgium). RR – respiratory rates; HR – heartbeat rates; ECG – electrocardiogram; LOA – limits of agreement.
