Procedure for reference and wearable device blood pressure measurements validation.

BPa measurement		Number
Initial BP measurementsb
	Take reference BP measurement (office BP)	Rc0
	Take wearable device BP measurement	Wd0
Validation BP measurements for accuracy evaluation
	Take first reference BP measurement (mean 24-hour ambulatory BP monitoring)	R1
	Take first wearable device BP measurement (mean 24-hour wearable device)	W1
	Take second reference BP measurement (mean 7-day home BP monitoring)	R2
	Take second wearable device BP measurement (mean 7-day wearable device)	W2

^aBP: blood pressure.

^bMeasurement R0 was not used in the evaluation of reference BP distribution and variability criteria. Measurements R0 and W0 were not used in the evaluation of the test device accuracy.

^cR: reference blood pressure device.

^dW: wearable blood pressure device.
