Fig. 1: Association between COVID-19 infection and the microbiota composition of Moroccan and French cohorts.
From: Gut microbiota alterations are linked to COVID-19 severity in North African and European populations
a Relative abundance of prokaryotic taxa in microbiota of Moroccan and French COVID-19 patients and healthy subjects at phylum, family, and genus levels. b Explained variance in Bray-Curtis distance (R²) calculated from PERMANOVA tests in Moroccan and French population. No significant associations were observed (FDR p value > 0.05) for other demographic details, covariates, or hospital course information. c Alpha diversity indices (Shannon’s H and Chao1) calculated from the raw taxonomic tables of Moroccan and French COVID-19 patients and healthy subjects. Wilcoxon tests were used to compare the groups. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001. d PCoA were built from the Bray-Curtis dissimilarity matrices constructed from the normalized abundance of species of each microbiota. Ellipses were drawn around the centroids of each emerging community at 95% (inner) and 97% (outer) confidence intervals.
