Table 1. 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 | Low ESS | ||||
---|---|---|---|---|---|
Sensitivity (CI) | Specificity (CI) | NPV (CI) | PPV (CI) | Accuracy | |
All | 54.0 (39.3-68.2) | 96.0 (94.1-97.5) | 95.9 (93.9-97.4) | 55.1 (40.2-69.3) | 83.4 |
LAD | 26.7 (12.3-45.9) | 96.6 (93.1-98.6) | 90.0 (85.2-93.6) | 53.3 (26.6-78.7) | 87.6 |
LCx | 94.1 (71.3-99.9) | 95.3 (89.4-98.5) | 99.0 (94.7-99.9) | 76.2 (52.8-91.8) | 95.2 |
RCA | 100 (29.2-100) | 95.9 (92.6-98.0) | 100 (98.4-100) | 23.1 (5.00-100) | 96.0 |
Test outcomes to detect low 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.
