Table 5.
Univariable association between the duration of the initial treatment course and survival of the koalas for chloramphenicol, doxycycline, and mixed/other treatments using Fisher’s exact test.
| Treatment | Duration (days) | Median duration (range) | Survived (%) | Died (%) | Odds ratio (95% CI) | p value |
|---|---|---|---|---|---|---|
| Chloramphenicol | < 28 1 | 14 (14–25) | 4 (7.0) | 4 (7.0) | 1.00 | 0.02 |
| ≥ 28 | 28 (28–45) | 44 (77.2) | 5 (8.8) | 8.8 (1.67, 46.57) | ||

CI = confidence interval. Koalas with unknown antibacterials, treatment duration, and/or outcomes were excluded from this table. 1 = reference category.
