Gut microbiota signatures of COVID-19. (A) Cladogram of microbial taxa differentially represented between COVID-19 patients and healthy subjects at phylum to family level. The diameter of each circle is proportional to the taxon abundance. (B) Linear discriminant analysis (LDA) scores of discriminating genera between groups (the logarithmic threshold for discriminative features was set to 3.0). Plots were obtained by LDA effect size (LEfSe) analysis.
