TB
Sputum-eligible participants who had valid Xpert-Ultra results from both S1 and S2 and were not culture-eligible (according to the non-IDP community definition) were classified as prevalent TB (yes or no) based solely on their Xpert-Ultra results (see above).Sputum-eligible participants who were culture-eligible (according to the non-IDP community definition) were classified as prevalent TB (yes or no) based solely on their culture results. Those who were culture-positive for Sputum-eligible participants with missing Xpert-Ultra data on one or both of the S1 and S2 sputum samples (a test result that was non-determinate or a sample that was not provided) were classified as having missing data on prevalent TB. It was assumed that participants who were not eligible to provide sputum samples did not have prevalent TB.
