Anti-self glycan antibodies have a different IgG subclass distribution compared to those against non-self glycans. Percentage of samples having antibody reactivity against antigens grouped in non-self glycan (blue bars) and self glycan (red bars) are shown for each IgG subclass. The different anti-non-self glycan and anti-self glycan IgG subclass antibody reactivities were determined using HPTLC-I (**: p < 0.01; ***:p < 0.001; Fisher's exact test).
