Figure 3

Incremental value of TESL and TPSS by multivariable logistic regression models. (a) In the single-vessel group, the peak systolic strain was a significant parameter in diagnosing left anterior descending artery (LAD) stenosis, and TESL and TPSS were also independent determinants in the logistic regression analysis. The addition of TESL and TPSS to the peak systolic strain significantly increased the model power. (b) In the multivessel group, the peak systolic strain was also a significant parameter in diagnosing LAD stenosis. However, the addition of TESL and TPSS did not generate a significant increase in the model power. The tables present the odds ratios and 95% confidence intervals.
