Figure 3. The scatter plots for association between gut microbiota and PAD. (A) family Family XI; (B) genus Lachnoclostridium; (C) genus Lachnospiraceae; (D) class Actinobacteria; (E) family Acidaminococcaceae; (F) genus Coprococcus2; (G) genus Ruminococcaceae UCG004; (H) genus Ruminococcaceae UCG010; (I) order NB1n. Note: SNP effects were plotted into lines for the inverse-variance weighted test (light blue line), MR-Egger (blue line), weighted median (green line), Simple mode (light green line) and Weighted mode (red line). The slope of the line corresponded to the causal estimation.
