2
At the same visit, blood pressure was measured with the participant in the seated position using a mercury sphygmomanometer.
3
The average blood pressure value was calculated from three systolic and diastolic blood pressure readings measured by mercury sphygmomanometer.
4
The ABI ratio was measured by using a pressure cuff of appropriate diameter, a standard mercury sphygmomanometer and a Doppler probe.
