Fig. 3: Differentially abundant taxa. Linear discriminant analysis (LDA) effect size (LEfSe) was performed on the microbial communities of the stool and oral swab samples.

a Histogram of the LDA scores for differentially abundant bacterial taxa in the stool sample between the patient and control groups. b Taxonomic cladogram of the gut microbiota. c Histogram and d cladogram of the oral microbiota. Green and red colors represent bacterial taxa that were significantly overrepresented in the STEMI patients and control groups, respectively.
