| Test | Sensitivity (P-value) | Specificity (P-value) | PPV (P-value) | NPV (P-value) | AUC (P-value) |
|---|---|---|---|---|---|
| Xpert vs CapitalBio assay | 0.502 | 1.000 | 0.796 | 0.642 | 0.605 |
| Xpert vs Parallel test | 0.480 | 1.000 | 0.824 | 0.585 | 0.582 |
| CapitalBio assay vs Parallel test | 0.171 | 1.000 | 0.631 | 0.316 | 0.284 |
Abbreviations: PPV, positive predictive value; NPV, negative predictive value; AUC, area under the curve.
