Data were arranged chronologically based on the date and time of the participant's assessment, and then divided into quintiles in order to assess the progressive effect of learning on measurement accuracy. Data are presented as mean ± standard deviation.

^*10 and 20 s PWV quintile 3 groups had 8 participants.
