Table 4. Diagnostic tests evaluating the test model (without side branches) ESS estimates versus the reference standard (i.e. using the entire coronary tree) ESS estimates.
Arteries | High ESS | ||||
---|---|---|---|---|---|
Proximal | Sensitivity (CI) | Specificity (CI) | NPV (CI) | PPV (CI) | Accuracy |
All | 44.7 (28.6-61.7) | 95.5 (91.4-98.0) | 89.0 (83.7-93.1) | 68.0 (46.5-85.1) | 86.6 |
LAD | 30.0 (6.7-65.3) | 89.3 (80.1-95.3) | 90.5 (81.5-96.1) | 27.3 ( 6.0-61.0) | 82.4 |
LCx | 0 (0-84.2) | 97.7 (88.0-100) | 95.6 (84.9-99.5) | 0 (0-97.5) | 93.5 |
RCA | 53.9 (33.4-73.4) | 100 (94.0-100) | 83.1 (72.3-91.0) | 100 (76.8-91.0) | 85.9 |
Test outcomes to detect high ESS regions in the proximal portions of the coronaries are depicted. All values in percentages [%]; CI: 95% confidence interval, NPV: negative predictive value, PPV: positive predictive value.
