Figure Lengend Snippet: Verification of autoantibodies by focused microarray A . Repeated detection of pooled samples displayed high reproducibility, with an averaged correlation coefficient of 0.95. Pooled samples comprised randomly selected samples from the Early-LUAD, BLD, and NHC groups (10 samples in each group). ***, P < 0.001 ( t -test for Pearson correlation coefficients). B . The top 10/top 15 IgG and IgM autoantibodies with the most significant elevation in Early-LUAD compared to BLD/NHC/Control are displayed. These most significant autoantibodies are ranked based on their FC on the vertical axis and sensitivity on the horizontal axis. C . A descending trend in the signal distribution of IgM autoantibodies across three representative samples from the Early-LUAD, BLD, and NHC groups, respectively. The images on the left visually depict the functionality of the focused microarray, while the 3D bar plots on the right show the distribution of normalized fluorescence intensities. D . IgG and IgM types of autoantibodies showed significantly higher levels in Early-LUAD compared to BLD. *, P < 0.05; **, P < 0.01 (Welch’s t -test). FC, fold change; NS, not significant.
