Fig. 6From: Gut microbiome changes in overweight male adults following bowel preparationMicrobial distribution at phylum level. (a) Phylum-level microbial composition of fecal community. Two phyla, Bacteroidetes and Firmicutes, are dominant within most individuals. (b) Scatter plots between Bacteroidetes and Firmicutes for each type at the three collection time points. The correlations between Bacteroidetes and Firmicutes at SB and D7 were negative (Spearman ρ = − 0.53 and − 0.45, respectively; P < 0.05). (c) The correlation between Bacteroidetes and Firmicutes in the Type 1 samples changed markedly from SB to D28 compared with the Type 2 samplesBack to article page
