Demographic characteristics of the study participants.

NOTE: Age distribution between the groups was compared using Kruskal-Wallis test. Percentage of male individuals and positive Quantiferon tests were analyzed using chi-square and Fisher’s exact tests respectively. IQR, interquartile range; NS, non significant; TB, tuberculosis. *Healthy donors and latent TB infection cases were not included in the statistical analysis for Quantiferon positivity, as the test status was part of the criteria to categorize these groups. †Percentage of individuals presenting with different sites of infection with the extra-pulmonary tuberculosis group were compared using chi-square test.
