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.
