Study of the Relationship between Microbiome and Colorectal Cancer Susceptibility Using 16SrRNA Sequencing

Figure 1

(a) Venn diagram of OUT and (b) dilution curve of the alpha diversity index. As is shown, the dilution curve of Sobs index with the curve is going to flatten out. (c) Principal component analysis (PCA) based on OTU abundance between groups CC and HC. x-axis, 1st principal component and Y-axis, 2nd principal component; 14.73% in brackets represents contributions of PC1 components to samples, 10.34% represents contributions of PC2 components to samples. A dot represents each sample, and different colors represent different groups (red: group CC and blue: group HC). (d) OUT rank curve.
