Forest plot of significant factors in the multivariate logistic regression to predict indeterminate results in the IGRA (QFT-GIT). Cases were divided according to the criterion for indeterminate results (Mitogen − Nil IFN-γ level < 0.5 IU/mL). For definitions of lymphopenia and hypoalbuminemia, refer to the Methods.
