Table 2.
Overall incidence of positive results to diagnostic tests for TB in BCG-vaccinated and control (non-vaccinated) badgers in the clinical field study. (Approximate F probability values <0.05 identify statistically significant differences between treatments from generalized linear models applied to data aggregated by social group.)
| test | treatment | % of incident cases (95% CI) | test-positive badgers | total number of badgers | approximate F probability |
|---|---|---|---|---|---|
| Stat-Pak | BCG | 4.5 (2.4–8.2) | 8 | 179 | 0.001 |
| control | 17.1 (10.8–25.9) | 14 | 82 | ||
| culture | BCG | 6.1 (3.4–10.8) | 11 | 179 | 0.50 |
| control | 8.4 (4.0–16.7) | 7 | 83 | ||
| Stat-Pak or culture | BCG | 8.4 (4.9–14.0) | 15 | 179 | 0.009 |
| control | 21.7 (13.5–32.9) | 18 | 83 | ||
| IFNγ | BCG | 28.1 (20.5–37.2) | 50 | 178 | 0.38 |
| control | 35.0 (23.1–49.2) | 28 | 80 |
