Due to the lack of corresponding experimental data on this type of cell, in this study, we used the ratio of IFN-γ to lymphocyte count to correct the levels of IFN-γ, and logistic multivariate regression analysis was performed on the corrected levels of IFN-γ in the Nil, TB antigen and mitogen tubes, as well as other variables such as gender, age, and PE and the risk variables of ATB were screened out. Here, IFNG is linked to tuberculosis.
