Fig. 6From: The underlying molecular mechanisms and biomarkers between periodontitis and COVID-19Immune cell composition generated by xCell-inferred enrichment score of cell types across periodontitis, COVID-19 and healthy controls. Compared with healthy controls, plasma cell levels were elevated in periodontitis and COVID-19 (*p < 0.05; **p < 0.01; ***p < 0.001)Back to article page
