Characteristic	Blood isolate clustered (n = 14)	Blood isolate unique (n = 6)	P value

TST ≥15 mm, n (%)	11 (79)	3 (50)	0.20
Received placebo vaccine, n (%)	8 (57)	5 (83)	0.26
Median CD4 at baseline, cells/μl	271	292	0.74
Median CD4 at time of disseminated tuberculosis, cells/μl	54^*	18^*	0.04
Polyclonal disease, n/N (%)	2/5 (40)	1/3 (33)	0.85

Value based on comparison of 16 evaluable CD4 counts, see text for definition.
