Fig. 2

ac, Plasma levels of IgM (a), IgG (b) and IgA1 (c) reactive to PPD, Ag85A, ESAT6 and CFP10, α-crystalline (HspX), GroES and LAM were quantified in ‘resisters’ (n = 40) and LTBI individuals (n = 39) with AUCs determined from MFIs generated using a customized Luminex assay, generated with three dilutions and plotted for each individual with medians and interquartile ranges depicted for each group. The statistical significance was calculated using the Mann–Whitney U test, and two-tailed P values are indicated. Dotted lines represent the median level detected in HIV-negative, healthy North American volunteers.
