Fig. 2: TOP TB assay results in respiratory specimens sourced at Boston Medical Center for the anonymized study (May/2013 to September/2013; TOP-positive = 18 [12.3%]) and the longitudinal clinical study (February/2014 to June/2014; TOP-positive = 16 [15.8%]).

All samples were positive for the 3ponA diagnostic primer (n = 34). Of these, 33 samples were also positive for the 2ponA genotyping primer. The figure shows the frequency distribution of Mycobacterium tuberculosis 2ponA variants for each study. Source data can be found in Tables S1 and S3.
