| Error term associated with TB prevalence† | –0.067 | 0.068 | 0.965 | 0.3259 |

*TB, tuberculosis. †If the error term is statistically significant, it indicates that there are differences in the prevalence rate of TB at the district level (but doesn’t identify which districts are different and the degree of difference). ‡If the error term is statistically significant, it indicates that there are differences in the prevalence rate of TB by origin (zone) of cases (but doesn’t identify which the degree of difference between origins).
