Key result
The PP-1000 pulse wave velocity measurement system demonstrated high reproducibility in healthy subjects, with a between-observer correlation for aortic PWV of r=0.93 and within-observer correlations ranging from 0.94 to 0.99.

Does the PP-1000 pulse wave velocity measurement system provide reproducible regional PWV values in healthy male subjects?
Effect estimate: r=0.93
p-value: p=<0.01
The PP-1000 system provides highly reproducible regional pulse wave velocity measurements in healthy subjects, supporting its potential for clinical application in evaluating arterial stiffness.
Lee et al. (2009) conducted an observational in Healthy (n=17). PP-1000 PWV measurement system vs. Between-observer and within-observer measurements was evaluated on Between-observer correlation coefficient for aortic PWV (r=0.93, p=<0.01). The PP-1000 pulse wave velocity measurement system demonstrated high reproducibility in healthy subjects, with a between-observer correlation for aortic PWV of r=0.93 and within-observer correlations ranging from 0.94 to 0.99.
