Table 3. Validation of accuracy of the two step classification of CAD (screening + algorithm) using structured data only, compared with the structured data + NLP.
Natural language processing = NLP; negative predictive value = NPV; positive predictive value = PPV.
| Disease cohort | Sensitivity | Specificity | PPV | NPV | Additional subjects classified with CAD (%) |
|---|---|---|---|---|---|
| IBD, structured data only | 59 | 99.6 | 90 | 98.1 | ref |
| IBD, structured + NLP | 73 | 99.6 | 90 | 98.6 | 17.2 |
| DM, structured data only | 84 | 96.2 | 90 | 93.8 | ref |
| DM, structured + NLP | 87 | 96.3 | 90 | 94.5 | 10.2 |
