Abstract

Wearable blood pressure (BP) monitoring devices which measure BP levels accurately both in and out of the office are valuable for hypertension management using digital technology. The authors have conducted the first comparison study of BPs measured by a recently developed wrist‐worn watch‐type oscillometric BP monitoring (WBPM) device, the “HeartGuide,” versus BPs measured by an ambulatory BP monitoring (ABPM) device, A&D TM‐2441, in the office (total of 4 readings alternately measured in the sitting position) and outside the office (30‐minutes interval measurements during daytime) in 50 consecutive patients (mean age 66.1 ± 10.8 years). The 2 BP monitoring devices were simultaneously worn on the same non‐dominant arm throughout the monitoring period. The mean difference (±SD) in systolic BPs (average of 2 readings) between WBPM and ABPM was 0.8 ± 12.8 mm Hg (P = .564) in the office and 3.2 ± 17.0 mm Hg (P < .001) outside the office. The proportion of differences that were within ±10 mm Hg was 58.7% in the office and 47.2% outside the office. In a mixed‐effects model analysis, the temporal trend in the difference between the out‐of‐office BPs measured by the two devices was not statistically significant. In conclusion, the difference between the WBPM and ABPM device was acceptable both in and out of the office.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In office-based setting, the mean difference in systolic blood pressure between the HeartGuide wristwatch and an ambulatory BP device was 0.8 ± 12.8 mmHg.

    “The mean difference (±s.d.) in systolic BP between both groups was 0.8 ± 12.8 mmHg in the office-based setting and 3.2 ± 17.0 mmHg in the ambulatory setting25.”
  • In ambulatory setting, the mean difference in systolic blood pressure between the HeartGuide wristwatch and an ambulatory BP device was 3.2 ± 17.0 mmHg.

    “The mean difference (±s.d.) in systolic BP between both groups was 0.8 ± 12.8 mmHg in the office-based setting and 3.2 ± 17.0 mmHg in the ambulatory setting25.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
