  • Participant who has been diagnosed and treated with antihypertensive medication.

  • Mean absolute difference (MAD) between the blood pressure (BP) value of the test device (CLB) and the reference device (CB), the cuff-wearing sphygmomanometer. According to the Institute of Electrical and Electronics Engineers standard, the accuracy of the cuff-less BP devise was assessed by the sufficient number of systolic blood pressure (SBP) rise and decline in the range of 0 to 30 mm Hg. The accuracy limit of BP estimation was determined by the MAD of BP (<7 mm Hg difference between the CLB and the reference device. DBP = diastolic blood pressure; PR = pulse rate recorded by CLB.
