Fig. 3. : magnitude of responses to Mycobacterium tuberculosis peptides. The bars represent the magnitude of response of each peptide (overall sum of spots of all individuals with positive responses). Positive responses > 30 spot forming cells (SFC) interferon (IFN)-γ/106 peripheral blood mononuclear cells (PBMCs) (p = 0.007, Mann-Whitney U test). TST+: tuberculin skin test-positive; TST-: TST-negative.
