Clustering and IS6110 copy number of M. tuberculosis isolates from Malaysia
| IS6110 copy no. | No. of isolatesa | Percentage of total isolates | No. of clustered isolates | % Clus-teringb | No. of clusters | Maximum cluster size (no. of isolates) |
|---|---|---|---|---|---|---|
| 1 | 77 | 17.5 | 77 | 100.0 | 3 | 63 |

a
Since repeat isolates from individual patients have been eliminated, the number of isolates corresponds to the number of patients.
b
Percent clustering is the number of isolates forming part of a cluster, for each copy number, as a percentage of the number of isolates with that copy number.
