Fig. 1.

Fecal microbiota composition and alpha diversity among stroke patients and controls. a Each bar represents one sample; phyla are indicated with colors and expressed in percentage of the total DNA reads. Only phyla that made up ≥ 5 of the total microbiota in at least one sample are included. On microbiota phylum level, ischemic stroke patients (n = 287) and cerebral hemorrhage (n = 37) showed a significant reduction in Firmicutes and Bacteroidetes, while Proteobacteria were enriched, compared with controls (n = 51). b Heatmap of the 20 most abundant bacterial genera in the dataset. Values and colors depicted in the graph display median relative abundance per group
