Figure 2. Proportion of TB patients initiated on anti-TB therapy based on test, by study phase.

The bars show the proportion of culture-positive TB patients in the baseline vs. the implementation phase started on anti-TB therapy based on rapid test results (i.e., smear in baseline phase and smear/Xpert in implementation phase; 60% vs. 71%, p = 0.055), empirically prior to hospital discharge (15% vs. 7%, p = 0.047), or based on culture results (6% vs. 7%, p = 0.92). The proportion of patients with culture-confirmed TB who were never treated during this study period was similar (19% vs. 15%, p = 0.42).
