Prevalence of inter‐arm difference in systolic blood pressure (IADSBP) ≥10 mm Hg in the cross‐sectional study sample. The chart shows the prevalence of IADSBP ≥10 mm Hg at the first, second, and third blood pressure reading, separately for the sequential (black columns) and simultaneous (grey columns) method. The prevalence of IADSBP ≥10 mm Hg decreased moving from the first to the third sets of readings for both methods and when using combinations of these readings.
