Table 1

Discriminatory power of the three different typing methods for a subset of 274 drug-resistant M. tuberculosis isolates from Sichuan, China.

Method	Number of types	Number of unique isolates	Number of clustered isolates	Number of clusters	Range of cluster size (number of isolates)	Number of clustered Beijing isolates	Number of clustered non-Beijing isolates	HGI
24-locus MIRU-VNTR	268	262	12	6	2	11	1	0.999
12 highly discriminatory loci	267	260	14	7	2	13	1	0.999
IS6110-RFLP	266	260	14	6	2-3	5	9	0.999
