Figure 2

Proportion of all smear positive TB patients with final treatment outcomes for all provinces, tracer vs. non-tracer subdistricts, Quarter 1 2007-Quarter 1 2009, South Africa. A significant difference was detected in tracer subdistricts (solid line) compared to non-tracer subdistricts (dashed line) in the proportion of treatment outcomes for patient default, completion, and failure among all smear positive TB patients with treatment outcomes recorded in the ETR. The p-value reported for each graph represents the significance of the tracer status by time interaction term to assess the change in linear trend of each treatment outcome comparing tracer versus non-tracer subdistricts over time. The y-axis of each graph in Figure 2 varies according to the baseline treatment outcome recorded for Q1 2007. The y-axes were not standardized on a 0-100% scale to allow for better visualization of the percent change in each treatment outcome from baseline to the end of the evaluation period in Q1 2009.
