Additional file 9: Figure S6. of ABO antigen and secretor statuses are not associated with gut microbiota composition in 1,500 twins

QQ-plot of the 9 linear mixed models comparing ABO and secretor phenotypes to taxon relative abundance. Expected –log10(P-values) are plotted (x-axis) compared to the observed –log10(P-values) along the y-axis. Tests significant at q ≤ 0.1 and q ≤ 0.05 thresholds are indicated with larger point sizes for linear mixed models 1-9 (A-E). Model descriptions can be found in the methods section. (PDF 103 kb)
