Subgroup Analysis of Treatment for Confirmed Tuberculosis within 14 Days after Presentation (Primary Outcome).^*

Subgroup	Intervention	Control	Unadjusted Rate Ratio (95% CI)†	Adjusted Rate Ratio (95% CI)‡
	number of patients
All patients	342	220	1.55 (1.16–2.08)	1.56 (1.21–2.01)
Sex
Male	234	147	1.59 (1.17–2.17)	1.59 (1.21–2.09)
Female	108	73	1.48 (1.02–2.15)	1.46 (1.03–2.07)
HIV infection status§
Positive	134	75	1.79 (1.13–2.83)	1.78 (1.15–2.77)
Negative	206	144	1.43 (0.94–2.18)	1.46 (0.98–2.18)

^*Shown are the counts of patients who received treatment for confirmed tuberculosis within 14 days after presentation in the 16-month intervention period (497 days). The rate ratio is the number of patients with the outcome per observation day in the intervention group as compared with the control group.

^†The unadjusted analysis was at the cluster level with adjustment for randomization strata (fixed effect, two levels).

^‡The adjusted analysis was at the cluster level with adjustment for cluster-level covariates (randomization strata [fixed effect, two levels] and the number of patients treated for confirmed tuberculosis within 14 days after presentation during the 12-month prerandomization period [linear term]).

^§The analysis excluded 1081 patients with unknown status regarding HIV infection.
