In the people with no history of TB, the amount of intact provirus in CD4+ T cells was not statistically significantly different by IGRA status (median 80; IQR, 35-255 for IGRA-positive vs 118; IQR, 21-279 for IGRA-negative per million CD4+ T cells,, P=0.65; Figure 1D). Here, CD4 is linked to tuberculosis.
