Fig. 3From: Screening and identification of a six-cytokine biosignature for detecting TB infection and discriminating active from latent TBCytokine levels detected from serum samples in the biomarker validation group. Levels of cytokines detected in serum samples from patients with active TB (ATB, n = 76), individuals with latent TB infection (LTBI, n = 69), and TB non-infected controls (CON, n = 71) in the biomarker validation group. Representative plots for TB antigen stimulated IFN-γ (IFN-γA), IP-10 (IP-10A), IL-1Ra (IL-1RaA) (a–c) and unstimulated VEGF (VEGFN), IP-10 (IP-10N), IL-12 (p70) (IL-12N) (d–f) are shown. Error bars in the scatter-dot plots indicate the medians and IQRsBack to article page
