Note: Probable cases of tuberculosis were also included as microbiological confirmation was not available for all cases.

TB, tuberculosis; IQR, interquartile range.

^†, Only includes participants with isolated pulmonary tuberculosis. The total number of pulmonary tuberculosis cases will be 171 (70.1%) if participants with both pulmonary and concurrent extrapulmonary tuberculosis are included.
