Comparison of gut microbiota diversity index between L-LDL-C group and H-LDL-C group patients with CRC. A Comparison of α-diversity index of gut microbiota between L-LDL-C group and H-LDL-C group in CRC patients. B Comparison of β-diversity index of gut microbiota between L-LDL-C group and H-LDL-C group in CRC patients. The horizontal axis represents the group, the vertical axis represents the diversity index value of the sample community within the group, and the color also represents the group. C PLS-DA analysis of gut microbiota in the L-LDL-C and H-LDL-C groups of CRC patients. The dots represent each sample of gut microbiota, the color represents the group, the horizontal and vertical axis scales represent the relative distance of each sample, and X variable 1 and X variable 2 represent the factors that affect the changes in gut microbiota composition of CRC patients in the L-LDL-C and H-LDL-C groups, respectively
