Table 3. 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 | ||||
---|---|---|---|---|---|
Sensitivity (CI) | Specificity (CI) | NPV (CI) | PPV (CI) | Accuracy | |
All | 73.9 (67.6-79.7) | 85.9 (82.1-89.2) | 85.7 (81.9-89.0) | 74.3 (67.9-80.0) | 81.2 |
LAD | 83.5 (74.3-90.5) | 81.8 (74.5-87.8) | 88.6 (82.0-93.5) | 74.5 (64.9-82.6) | 82.5 |
LCx | 22.2 (2.81-60.0) | 85.2 (77.4-91.2) | 93.3 (86.8-97.3) | 10.5 (1.30-33.1) | 80.7 |
RCA | 70.4 (61.2-78.6) | 91.0 (84.8-95.3) | 78.1 (70.7-84.3) | 87.1 (78.6-93.2) | 81.5 |
Test outcomes to detect high ESS regions in the entire length of the coronaries are depicted. All values in percentages [%]; CI: 95% confidence interval, NPV: negative predictive value, PPV: positive predictive value.
