Figure 2

Impact of a discrete 2-year active case finding campaign in India. Panel A illustrates the incidence rate (dark green), case detection rate (light green), and mortality rate (red) for a baseline/counterfactual scenario (dashed) compared against an intervention scenario (solid) in which TB case detection is increased, through active case finding, by 25% from the cases detected in the first year (2012). Panel B shows the cumulative incidence (per 100,000) for both the intervention (solid) and baseline (dashed) scenarios with the area between the two curves representing the cases averted through active case finding. Panel C shows the cases averted by the intervention (green), and DALYs averted by the intervention (brown) - a function of cases averted and mortality averted by intervention. The grey shading highlights the component of the intervention effect that would be observable during the course of a 2-year intervention study.
