Table 5 Proportion of TB transmitted with varying definition of mixed cluster origin
From: Migrant tuberculosis: the extent of transmission in a low burden country
* | Likely origin of clusters (based on numbers of Danes/migrants in the individual cluster) | Proportion of TB cases likely due to transmission | Odds ratio | ||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|
Danish (most Danes) | migrant (most migrants) | uncertain (even number) | |||||||||
Ethnic composition of cluster | Mixed | Danish | Mixed | Migrant | Mixed | % (95% CI) | % (95% CI) | OR (95% CI) | |||
Ehnicity of case | Migrants n | Danes n | Danes n | Migrants n | Danes n | Migrants n | Migrants n | Danes n | From migrants to Danes | From Danes to migrants | |
