Identification of differentially expressed MERGs. A The petal plot identifies 44 MERGs. B Volcano plot showing differentially expressed MERGs between periodontitis and healthy gingival tissues. C Expression levels of 44 MERGs in gingival samples. Rows and columns denote MERGs and samples, respectively. D Correlation heatmap showing correlations among 44 MERGs, where “×” indicates no correlation
