Description: FIGURE 3 LEfSe analysis revealed the specific taxa changes in high-risk individuals (Pre) and RA patients. LefSe analysis was applied to identify differentially abundant taxa and for which the LDA scores more than 3 are shown (B). LefSe, the LDA effect size. *p < 0.05; **p < 0.01; and ***p < 0.001.
