Quantitative Assessment of Blood Pressure Measurement Accuracy and Variability from Visual Auscultation Method by Observers without Receiving Medical Training

<div>Histograms of measurement errors of SBP and DBP from each individual observer using the two measurement methods: traditional manual method and visual auscultation method. There are a total of 900 comparisons for each measurement method (from 30 Korotkoff recordings, 10 observers, and 3 repeated determinations).</div>
