Figure 3 (A–D) Bland-Altman plots of RR and heartbeat rates HR between ECG and radar for the male and female subgroups of individual user 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 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.
