During a secondary analysis, the authors discovered 147 duplicate entries in their study database that consists of over 30,000 entries. The duplication of entries was randomly distributed and after reanalysis only minor changes in effect measures, which do not impact the authors’ conclusions, were observed. For example, the notification rate ratio for laboratory confirmed TB (the study’s primary endpoint) was 1.59 (95% CI 1.31–1.88) in the original analysis and 1.60 (95% CI 1.31–1.89) in the revised analysis. A revised version of Table 4 is presented below.
