Fig. 1From: Seven-CpG-based prognostic signature coupled with gene expression predicts survival of oral squamous cell carcinomaFlow chart indicating study design. We identified candidate CpG sites from 32 paired OSCC and adjacent non-tumor tissues by methylation 450k assay in the discovery set. Then, we excluded a large proportion of CpG sites that were unrelated to survival and developed prognostic scores by SIS. The seven-CpG-based classifier was validated in two independent datasets. Relationships between methylation and gene expression were also analyzed in the training datasetBack to article page
