*Moran’s I statistics with z score test value to detect the spatial distribution of tuberculosis (TB) in the 2 populations. A statistically significant (z score >1.96) estimate of I indicates that nearby districts (within 10 km) have a similar prevalence rate of TB and the cases are likely to cluster at the district level.
†Statistically significant, p<0.05 as measured by z score >1.96.
