Significant associations between microbial clades with sample metadata. a Heatmap summarizing all the significant associations between microbial clades and sample metadata. Color key: -log (q-value) * sign (coefficient). Cells denoting significant associations are colored (red or blue) and overlaid with a plus (+) or minus (−) sign indicating the direction of association: qPCR_barrier_function (−), negative correlation between microbial clade abundance and qPCR_barrier_function (PC1 of PCA); qPCR_immune_response (−), negative correlation between microbial clade abundance and qPCR_immune_function (PC1 of PCA); plasma_nutrients (+), positive correlation between microbial clade abundance and the levels of plasma_nutrients (PC1 of PCA). b The negative correlation between the relative abundance of Megasphaera and qPCR_barrier_function (PC1 of PCA). c The negative correlation between the relative abundance of Megasphaera and qPCR_barrier_function (PC1 of PCA). Of note, the gut immune gene expression levels were negatively correlated with PC1 of the PCA, which decreased as PC1 of the PCA increased (Additional file 3: Table S2). Hence, the relative abundance of Megasphaera shows a positive correlation with immune gene expression level. d The positive correlation between the relative abundance of Megasphaera and Bacteoides and plasma_nutrients (PC1 of PCA), respectively. FDR, false discovery rate; f__, family. The significant association was set at FDR < 0.25
