Microbiota biodiversity. a Alpha diversity. Bigger indexes of the observed species and Chao reflect greater richness, whereas a bigger Shannon index reflects greater diversity. b Similarities. “Between” shows the differences between groups, whereas the rest show differences within groups, R > 0 indicates differences between groups were more obvious than within groups, P value < 0.01 indicates significance. c OTUs based PLSDA. ADONIS, Fa-NC, R2 = 0.11797, P = 0.001 (***); Fa-Fb, R2 = 0.05057, P = 0.001(***); Fb-NC, R2 = 0.18593, P = 0.001(***). OTU, operational taxonomic unit; PLSDA, partial least squares discrimination analysis; Fa, CRC patients before treatment; Fb, CRC patients after surgery; NC, normal controls
