BCG-specific IFN-γ responses were higher in blood from Highly TB-Exposed Infected children at 24 h (median 50.44 pg/ml, IQR 23.15–75.36) than Highly TB-Exposed Uninfected children (median 30.06pg/ml, IQR 14.64–50.86, p = 0.0232, Fig. 3a, Table 3, Supplementary Fig. 4). The gene discussed is IFNG; the disease is tuberculosis.
