Key result
Simultaneous 24-h ABPM on both arms showed mean differences of 1.16 mmHg (SBP) and 1.32 mmHg (DBP) with wide limits of agreement, revealing notable measurement uncertainties.
Why the study?
Although 24-h ABPM is the gold standard in hypertension diagnostics, the measurement accuracy of widely used devices warranted examination.

Simultaneous 24-h ABPM on both arms reveals notable measurement uncertainties that can significantly influence hypertension grading and dipping pattern classification.
Bothe et al. (2023) conducted an observational in Healthy (n=52). Simultaneous 24-h ambulatory blood pressure measurement (ABPM) vs. Left vs right arm was evaluated on Mean differences between simultaneous measurements for SBP and DBP (MD 1.16 mmHg for SBP and 1.32 mmHg for DBP). Simultaneous 24-h ABPM on both arms showed mean differences of 1.16 mmHg (SBP) and 1.32 mmHg (DBP) with wide limits of agreement, revealing notable measurement uncertainties.
