Pearson analysis showed no correlation between anti-EIF3A antibody and AFP biomarker (Pearson r = 0.0732, Fig. 5A left panel); however, anti-SF3B1 autoantibody, another tumor-associated autoantibody biomarker reported in our previous study28, showed a positive correlation with anti-EIF3A antibody (Pearson r = 0.5344), but not the same (Fig. 5A right panel). Here, AFP is linked to neoplasm.
