Fig. 2From: Correlation between intestinal flora disruption and protein–energy wasting in patients with end-stage renal diseaseCorrelation between biochemical markers and the predicted amino acid metabolic pathway of the HD group (A) and the PD group (B). The abscissa represents the flora diversity index and blood biochemical markers, and the ordinate represents the amino acid metabolism. The color scale bar ranges from − 5.0 to 5.0, with red, orange, and yellow representing low, medium, and high correlations, respectivelyBack to article page
