Global view of the gut microbiota (****P < .0001, ***P < .001, **P < .01, *P < .05). a Relative number of protein groups identified in the contents of the three gut sections. b Boxplot of protein groups which were relatively quantifiable by label-free quantification (LFQ). Number in plot represents the number of protein groups in the boxplot. c Alpha diversity of 16S rRNA gene sequencing data at OTU level. Richness based on OTU numbers (left) and Shannon-effective diversity index (right). d Beta-diversity of 16S rRNA gene sequencing data at OTU level based on NMDS analysis (P calculated by PERMONAVA on the read count data) (error bars are SEM)
