Table 3 Recording of cuff size used and measured arm circumference, mean arm circumference, proportion of miss-cuffed subject, and proportion of identical readings

From: Challenges in standardization of blood pressure measurement at the population level

Pilot survey Recorded cuff size used Arm circumference measured and recorded (M = measured, not recorded, B = measured and recorded, N = Not measured) Mean arm circumference (min,max) Proportion of miss-cuffed subject (based on optimal arm circumference reported on the cuff) Proportion of identical readings between 1st and 2nd measurement Proportion of identical readings between 2nd and 3rd measurement
