Treatment and study plan

PWV measurement

Other

Patient will have its PWV measured with the reference (the SphygmoCor) and by stepping on Withings bathroom scales WBS08 and WBS12.

Primary outcomes

  1. PWV measurement bias

    Time frame: 1 year

    Difference between the PWV measured and the PWV reference (m.s-1)

  2. PWV measurement deviation

    Time frame: 1 year

    The standard deviation of the difference between the PWV measured and the PWV reference (m.s-1)

Secondary outcomes

  1. Safety use

    Time frame: 1 year

    The percentage of participant having adverse effects over the total number of participant included.
