The levels of IFN-γ and IP-10 were significantly higher in QFT-IT TB antigens stimulated, as well as QFT-IT mitogen stimulated samples when compared to QFT-IT NIL samples. Box and Whisker plots show range, inter-quartile range and median. The difference between the groups was calculated by Kruskal-Wallis test. *significant difference p<0.001 compared to unstimulated sample, # significant difference p<0.001 compared to QFT-IT TB specific antigens stimulated sample.
