Fig. 3From: Transcriptomics and methylomics in chronic periodontitis with tobacco use: a pilot studyScatter plot of DNA methylation versus gene expression. The x and y axes present the log2-scaled ratios of DNA methylation and gene expression, respectively. Solid and dashed lines indicate the regression of smoker/periodontitis (SP) vs. smoker/non-periodontitis (SN) and of SN vs. non-smoker/non-periodontitis (NN)Back to article page
