T-cell assays with BCG r32kDa: Stimulation Indices and Interferon-γ levels in different age-groups of BCG-vaccinated children (n = 45). Definition of abbreviation: IFN-γ = Interferon – gamma, SI = Stimulation Index. Statistical Significance between mean values of IFN-γ levels (pg/ml): (a) < 6 years & 9–12 years (3316 ± 718 & 1360 ± 344; p < 0.003). (b) 6–8 years and 9–12 years (2880 ± 733 & 1360 ± 344; p < 0.01). Statistical Significance between mean values of SI: (a)<6 years & 9–12 years (5.69 ± 2.21 & 2.70 ± 1.13; p < 0.0002) (b) 6–8 years & 9–12 years (4.36 ± 2.10 & 2.70 ± 1.13; p < 0.013)
