Association of bacterial gene abundance with BCAA serum levels and HOMA-IR. A heat map of the partial Spearman’s rank correlation coefficient between genes involved in BCAA biosynthesis and serum levels of BCAA. B heat map of the partial Spearman’s rank correlation coefficient between genes involved in BCAA transport and serum levels of BCAA. C heat map of the partial Spearman’s rank correlation coefficient between genes involved in BCAA transport and HOMA-IR. P-values were calculated using partial correlations adjusted for Model 1: age and sex. Model 2: Model 1 + body fat percentage. False discovery rate (FDR) adjusted *P < 0.05, **P < 0.01
