Table 2 The comparison of Urease test and histopathology with the presence and absence of PPI.
Test | Sensitivity (95% C.I.) | Specificity (95% C.I.) | PPV (95% C.I.) | NPV (95% C.I.) |
|---|---|---|---|---|
Urease Test with PPI | 43.3% (30.9–50.6%) | 86.4% (69.5–96.2%) | 81.3% (58–94.8%) | 52.8% (42.4–58.3%) |
