Association between treatment failure or relapse and active disease caused by Beijing vs. other genotypes of Mycobacterium tuberculosis, Tuberculosis Trials Consortium Study 22*

Outcome Disease caused by Beijing genotype, n = 57 Disease caused by other genotype, n = 303 Odds ratio (95% CI) p value
Cure (n = 296)
42 (14)
254 (86)
1.9 (0.9–3.6)
Failure or relapse (n = 64) 15 (23) 49 (77)
Failure (n = 8) 1 (13) 7 (88) 0.9 (0.1–6.3) 1.00
Relapse (n = 56) 14 (25) 42 (75) 2.0 (1.0–4.0) 0.04

*The Tuberculosis Trials Consortium Study enrolled patients during 1995–1998. Participants in the case–control study were selected from among 1,004 HIV-infected participants. CI, confidence interval.
