TABLE 5.
SUBGROUPS WITH AN AVERAGE MODEL-PREDICTED PROBABILITY OF LMD THAT IS ≤ 2.5% DEFINED USING MODALITY SPECIFIC VARIABLES
| Subgroup definition | N | Mean Predicted Probability (Bootstrapped 95% confidence interval) |
|---|---|---|
| Female; Nuclear | 508 | 0.024 (0.018–0.026) |
| Female; Stress Echo | 446 | 0.025 (0.019–0.028) |
| Female; Nuclear; Summed difference score <10 | 389 | 0.021 (0.016–0.023) |
| Female; Stress Echo; Number of ischemic segments ≤5 | 361 | 0.021 (0.016–0.024) |
The following variables were used to define subgroups: Sex, age (categorized as ≤55, ≤65, and ≤75), prior MI, imaging modality (Nuclear, Stress Echo, and ETT). Modality specific variables included: Summed difference score on Nuclear≥ 10; Severe or Moderate Anterior Ischemia on Nuclear; Number of ischemic segments (categorized as ≤3, ≤5) on Stress Echo; TID (Transient ischemic dilation in the LV) on Stress Echo; Maximum ST Depression in Any Lead on ETT (categorized as ≤2, ≤3). Only subgroups including at least 350 participants were considered.
