Definition of abbreviations: HD = healthy donors; LTBL = patients with latent tuberculosis and 30∼80 SFCs; LTBH = patients with latent tuberculosis and 110∼400 SFCs; TB = pulmonary tuberculosis patients; TP = patients with tuberculosis pleurisy; CA = pulmonary cancer patients; Total No. = total number of participants in each group; TST = tuberculin skin test; SFCs = Mycobacterium tuberculosis (M.tb)-specific IFN-γ spot-forming cells.
The total number of recruited participants in each group included separated samples for microarray analysis and further validation.
