The ELISPOT assay performed in TB/HIV patients. The results of IFN-γ-producing cells in response to the specific antigens for a PPD, b ESAT-6 c 38 kDa/CFP-10 are expressed in log10 for spot forming cells (CFS). The colored points represent the magnitude of the response, and the gray points non-responders. Horizontal lines represent the median values. The statistical difference in the median number of CFS between consecutive visits was assessed through the Wilcoxon signed-rank test (***p < 0.01;**p < 0.05 and *p < 0.1). The results were also expressed as the percentage of individuals responsive to the antigens d PPD, e ESAT-6 and f 38 kDa/CFP-10, and individuals were considered responders with ≥50 spots/106 cells. The Exact McNemar test (***p < 0.01;**p < 0.05 and *p < 0.1) was used to assess the difference of the response between consecutive visits
