OTUs and taxa differing between non-periodontitis (upper panel) and periodontitis (lower anel) sites. a, c Heat map with the OTUs showing a p value of less than 0.05 when comparing relative abundances between control and SLE subjects. Subjects are shown in columns, while OTUs appear in rows. Blue asterisks indicate OTUs with decreased proportions in SLE patients, while red asterisks indicated OTUs with increased proportions in SLE in relation to respective controls. b, d The graphic representation of differences in the relative abundances of species represented in the heat maps
