Naoki Watanabe et al. BTS 2017;2:631-642 Validation and Reproducibility of CLB According to the IEEE 1708-2014 Standard Under Static and Dynamic Conditions Cumulative systolic blood pressure (SBP) dataset was obtained under (A and B) static (n = 386), (C and D) BP rise (n = 182), and (E) reproducible (retaking BP measurements on the same examinee 1 month later, n = 262) conditions. Linear correlation analysis was used to assess the association between the 2 measures. The correlation coefficient is given by r. The results of analyzing diastolic BP data are shown in Supplemental Figure 2. To assess the agreement of BP data measured by using CLB with those recorded by using a cuff-based sphygmomanometer, all BP data were assessed by using a Bland-Altman plot. Scatter plots of difference in SBP between CB and CLB under (B) static conditions, (D) dynamic conditions, and (F) for reproducibility assessment are shown. The average difference in SBP between the CLB and the CB is indicated by solid lines. Dotted lines indicate the 95% limits of agreement (mean ± 2 SDs of the difference in SBP) between the CB and the CLB. The agreement limits of SBP were: (in mean ± 2 SDs): (B) static, −0.3 ± 13.2; (D) BP rise, −2.1 ± 15.0; and (F) reproducibility, −0.8 ± 18.4. Abbreviations as in Figure 1. Naoki Watanabe et al.
