- Brief Summary
In total, 118 patients were evaluated. The prevalence of Doppler ABI 0.90 was 45.8%. Taking the Dop-ABI as the reference, the sensitivity, specificity, accuracy, positive and negative predictive values of oscillometric ABI during the first measurement by the first observer were 89.1%, 94.4%, 94.1%, 91.8%, and 92.4%, respectively.

- Primary Outcome Measures
Name Time Method Sensitivity, specificity, PPV, NPV, and Prevalence of the oscillometric method to detect a low (<0.90) ABI were determined by usual formula, taking the Doppler method as the reference.
- Secondary Outcome Measures
Name Time Method The intra and interobserver variability of measurements were first assessed by the determination of the intraclass correlation coefficient (ICC) of agreement for each method. In order to determine methods with the best reproducibility (the lowest variability), 95% CI of these ICCs were then compared. A second analysis of intra- and inter-observer reproducibility were made by the Bland and Altman's method.
