Predictors of MACE: Multivariable Study of Strain Variables
| Odds Ratio (95% CI) | p Value | |
|---|---|---|
| Segments with altered CS, n | 0.88 (0.56–1.38) | 0.60 |
| Segments with altered LS, n | 1.14 (0.91–1.41) | 0.30 |
| Segments with altered RS, n | 1.12 (0.73–1.71) | 0.70 |
| Global CS, % | 1.25 (0.89–1.77) | 0.90 |
| Global LS, % | 1.25 (1.14–1.36) | <0.001 |
| Global RS, % | 1.08 (0.96–1.22) | 0.50 |
To avoid variable overfitting and to select the strain variable with the highest prognostic value, the first multivariable analysis included only strain indexes.
CI = confidence interval; other abbreviations as in Tables 1 and 3.
