Simultaneous versus sequential BP measurements yield different device-observer differences yet identical validation grades; leaves open optimal protocol standardization.
Does the method of measurement (simultaneous vs sequential) affect the validation grading of the Daypress 500 blood pressure recorder compared to observer readings?
Simultaneous and sequential measurements yield different device-observer differences but result in the same validation grading for the Daypress 500 device when appropriate criteria are applied.
