Determination of the most distinguishable plasma anti-GPL-core antibody isotype for NTM-PD. Eight plasma samples from patients with non-tuberculous mycobacterial pulmonary disease (NTM-PD), Mycobacterium tuberculosis pulmonary disease (MTB-PD), and other bacterial pulmonary disease (Oth-PD) and healthy controls (HCs) were quantified for anti-GPL-core antibodies using indirect ELISA. The concentration of anti-GPL-core IgM (A), IgG (B), or IgA (C) antibody isotypes is shown with a line representing the median and interquartile range. Statistical differences among sample groups were tested using the Kruskal–Wallis test, and only significant P-values are shown in the figure.
