Table 2. Comparison of sensitivity and specificity of the examination methods for diagnosing PVD and urovagina.
| Examination objective | Examination methods | Sensitivity | Specificity | Kappa (95% CI) | P-value |
|---|---|---|---|---|---|
| Urovagina | Gloved-hand | 100 | 95.0 | 0.70 | 2.5 × 10–20 |
| (vs. Speculum) | (0.55–0.84) | ||||
| PVD (VDS 2–5) | Speculum | 84.6 | 97.8 | 0.80 | 2.4 × 10–37 |
| (vs. Metricheck) | (0.67–0.92) | ||||
| Gloved hand | 92.9 | 91.9 | 0.64 | 2.4 × 10–22 | |
| (vs. Metricheck) | (0.51–0.77) |
