Accuracy of Vital Signs Measurements by a Smartwatch and a Portable Health Device: Validation Study

These data have previously been presented by Van Helmond et al [12] and are reproduced with permission. Validation study: participant characteristics (n=85). The Bodi Metrics tricorder failed in 6 (7%) participants for a total of 13 (5%) of the maximum 255 BP measurements that could have been obtained in the 85 participants. The average absolute difference between the Bodi Metrics tricorder and the reference was 5.3 (SD 4.7) mm Hg for SBP (Figure 4).
