Figure 6 (A) Bland-Altman plots of HR for the BMI groups between ECG and radar measurements. 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). (B, C) Bland-Altman plots of HR for male and female BMI groups between ECG and radar measurements. Underweight was defined as BMI <18.5, normal weight was defined as 18.5≤ BMI <24, overweight was defined as 24≤ BMI <27, and obese was defined as 27≤ BMI. 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). HR – heartbeat rates; BMI – body mass index; ECG – electrocardiogram; LOA – limits of agreement.
