Beta Diversity Analysis of the Oral Microbiome in COVID-19 vs Non-COVID Individuals: Figure presents the beta diversity analysis of the oral microbiome in COVID-19 and non-COVID individuals. (A) Beta diversity (Bray–Curtis) plot, comparing the microbial community composition between the two groups. (B) PCoA plots based on Jaccard distance and Bray–Curtis dissimilarity, illustrating the clustering of samples and the separation between COVID-19 and non-COVID groups. (C) PCoA (Bray–Curtis) PERMANOVA results, providing statistical validation of the observed differences. (D) PCoA (Jaccard) ANOSIM results, offering additional statistical validation. (E) Scatter plot of beta diversity vs. genera abundance (Streptococcus and Lactobacillus), highlighting the relationship between community composition and the abundance of key genera.
