Bayesian analysis estimates of diagnostic test parameters in dogs
| Diagnostic test | 95% confidence interval | |
|---|---|---|
| Sensitivity | Specificity | |
| IFA | 99.4 (98.86‐99.7) | 99.8b (99.3‐99.9) |
| SNAP | 90.5ab (85.0‐94.9) | 98.7ab (95.9‐100) |
| VetChek | 94.5a (90.9‐98.7) | 96.0a (91.9‐98.8) |
| VetScan | 83.3b (75.9‐89.6) | 99.3b (97.4‐99.9) |
| ZnSO4 | 88.7b (82.3‐93.7) | 95.5a (91.6‐98.3) |
The sensitivity and specificity of each test in dogs with 95% confidence intervals (CI) estimated by Bayesian analysis. Within columns, different letters are significantly different (McNemar's P < .05). Cells without superscripts had no significant differences.
