Flow chart of the study protocol.

<p>We screened 3,571 subjects who underwent QuantiFERON-TB Gold In-Tube testing (QFT-GIT) testing more than once. Of these subjects, patients who were under 18 years old (n = 127) or who underwent QFT-GIT more than twice without consistent results (n = 53) were excluded. After exclusion, 3,391 patients were enrolled in the study in which 1,265 (37.3%) had a positive QFT-GIT result, 266 (7.8%) had an indeterminate result, and 1,860 (54.9%) had a negative result.</p
