Estimated trade-off of sensitivity and specificity
| CEDRA score | Sensitivity (%) | Specificity (%) | # of false positives per 100 patients | # of missed TEDs per 100 patients |
|---|---|---|---|---|
| X | 100 | 0 | 95 | 0 |
| 2 | 98 | 39 | 58 | 0 |
| 4 | 90 | 72 | 27 | 1 |
| 8 | 54 | 95 | 5 | 2 |
| 12 | 20 | 100 | 0 | 4 |
Data based on the initial “training” sample from Kleindienst et al. (2017) and an assumed TED prevalence of 5% for illustrative purposes. The first row represents every patient receiving a medical evaluation, and assumes the physician would catch every targeted ear disease (TED). Subsequent rows show different CEDRA cut-off scores and the estimated outcomes.
