Comparison of gut microbes in patients with pancreatic cancer and healthy people. (A)Microbial richness based on the Sobs index; (B-C)Index of community richness; (D-E)Index of community diversity; (F)Microbial sequencing coverage index. (G)Non-metric multidimensional scaling (NMDS) is a multidimensional data down scaling method used to analyze similarities and differences between pancreatic cancer and healthy people. According to the NMDS Bray-Curtis similarity diagram, the two-dimensional stress value is 0.221. (H)Bubble plot showing differences in abundance of the six most abundant genus level in the gut microbiota of patients with pancreatic cancer and healthy humans.Different colors represent different bacterial groups, and the size of the circles indicates the relative abundance of each bacterial group. ^*: P < 0.05; ^**: P < 0.01; ^***P: <0.001. (A-D, F)using a one-tailed Mann-Whitney test.(E, H)using an unpaired two-tailed Student’s t test
