Correlation analysis between gut microbiota and glucose/insulin levels. (A) The correlation between abundance of gut microbiota at genus level and glucose/insulin levels were determined by Spearman correlation analysis. (B) The correlation between abundance of gut microbiota at species level and glucose/insulin levels were determined by Spearman correlation analysis. (C) Heatmap and clustering of all samples based on functional composition of the metatranscriptome. (D) The correlation between functional composition of the metatranscriptome and glucose/insulin levels were determined by Spearman correlation analysis.
