Aneroid monitors may be preferred for home BP; extends RCT evidence guiding device selection over digital alternatives.
Do digital and aneroid home blood pressure monitors provide precise measurements compared to a mercury sphygmomanometer in ambulatory patients?
Aneroid home blood pressure monitors demonstrated better precision than digital monitors compared to a mercury standard, highlighting the need for initial calibration of home devices.
Johnson et al. (1999) studied this question.
