Fig. 1From: Identification of potential CpG sites for oral squamous cell carcinoma diagnosis via integrated analysis of DNA methylation and gene expressionCompared with the OSCC samples without CIMP, the samples with CIMP presented lower survival probability. a We identified the optimal cluster number as 3 via within-cluster sum of squares method. b The heatmap of DNA methylation level of clusters 1, 2, and 3. c Survival curves of clusters 1, 2, and 3. d Survival curves of samples with/without CIMPBack to article page
