Table 9. Intra-class correlations coefficients (ICC) and 95% confidence intervals (95% CI) between baseline (BASE) brachial artery diameter (BAD), peak response (PR) BAD, and estimated flow-mediated dilation (FMD) between Brachial Analyzer (BA), Funky Work Station (FWS), and the Multi-Ethnic Study of Atherosclerosis (MESA) FMD software tools.
Type of ICC | Base BAD (mm) | Peak-Response BAD (mm) | Flow-Mediated Dilation (%) |
---|---|---|---|
BA versus FWS (95% CI) | 0.95 (0.92, 0.97) | 0.93 (0.89, 0.95) | 0.47 (0.20, 0.65) |
BA versus MESA FMD (95% CI) | 0.91 (0.86, 0.94) | 0.90 (0.85, 0.93) | 0.38 (0.06, 0.59) |
FWS versus MESA FMD (95% CI) | 0.94 (0.92, 0.96) | 0.94 (0.91, 0.96) | 0.76 (0.64, 0.84) |
