Outcomes According to Study Group

	Xpert MTB/RIF	Fluorescence Microscopy	Relative Risk	95% CI	P Value
Outcome	n = 182	n = 172
Compositea	17 (9.3)	21 (12.2)	0.77	.42–1.40	.39
Early mortality	11 (6.0)	17 (9.9)	0.61	.29–1.27	.19
ART-associated TBb	6 (3.3)	6 (3.5)	0.95	.31–2.89	.92

Abbreviations: ART, antiretroviral treatment; CI, confidence interval; MTB, Mycobacterium tuberculosis; RIF, rifampin; TB, tuberculosis.

^a The primary endpoint was a composite of mortality and ART-associated tuberculosis.

^b Two individuals with ART-associated TB also died; these patients were counted only as deaths for purposes of the composite outcome.
