Fig. 2From: Pleural IFN-γ release assay combined with biomarkers distinguished effectively tuberculosis from malignant pleural effusionMtb elicits elevated IFN-γ responses in PFMCs than PBMCs in TPE patients. The matched PBMCs and PFMCs from TPE (n = 143) patients were stimulated with ESAT-6 protein (a) and peptide (b), and Mtb-specific IFN-γ responses were determined using ELISPOT reader. The paired t test was used to compare the differenceBack to article page
