Fig. 11From: Exploring the potential link between MitoEVs and the immune microenvironment of periodontitis based on machine learning and bioinformatics methodsIdentification of two distinct subtypes of hub MERG expression patterns in periodontitis. A Consensus clustering cumulative distribution function (CDF) for k = 2–9. B Relative change in the area under the CDF curve for k = 2–9. C Heatmap of the cooccurrence ratio matrix of periodontitis samples. D Principal component analysis of MERGs in subtype 1 and subtype 2. E Differences in the expression of hub MERGs between subtype 2 and subtype 1; ***P < 0.001Back to article page
