Figure 9

Analysis of RDA correlation between inflammatory factors and intestinal microorganism genus level where the dots represent the 36 samples (). Red rays represent the two environmental factors, IL-6 and TNF-α, and blue rays represent different species. The length of the rays represents the degree of their influence on the sample communities, and the direction of the rays represents the direction of increasing abundance. If the angle between the two rays is acute, it means there is a positive correlation; if it is obtuse, then there is a negative correlation; and if it is right angle, there is no correlation.
