TreeAge model outline for ACF and semi-PCF.
Each branch represents one possible instance. The comment below the node indicates the possibility of each node. The total cost of the branch is written next to the terminal node. CXR = chest X-ray, ACF = active case finding, semi-PCF = passive case finding, F/U = follow-up, TB = tuberculosis, SC = sputum culture test, AFB = acid-fast bacillus.

Impact of parameters used in this model on the cost-effectiveness of ACF with CXR and semi-PCF with CXR.
The bars represent the incremental cost-effectiveness ratio at the lower (black bar) and higher (gray bar) values for each variable. TB = tuberculosis, CXR = chest X-ray, ACF = active case finding, semi-PCF = passive case finding, SC = sputum culture test.
