Methods

We studied 31 participants (9 women) with a mean age of 47.67±12.55 years, who were submitted to sequential measures of carotid–femoral PWV by two experienced operators. The evaluations were made by randomly switching between the manual method, the Complior first generation, and the Complior SP (third generation).

Results

The analysis of concordance of measurements of PWV showed strong intraobserver and interobserver correlations. The intraobserver correlation coefficients were 0.984, 0.977, and 0.966, respectively, for manual evaluation, the Complior first generation, and the Complior SP (P< 0.0001). In the case of interobserver reproducibility, we found correlations of 0.940, 0.979, and 0.974, respectively, for manual evaluation, the Complior first generation, and Complior SP (P< 0.0001). Good indicators of reproducibility were also a withdrawal of the Bland–Altman analysis, with most …
