ROC analysis discriminating OSCC vs normal healthy donors using easyROC as a webtool, showing the three best performing CpGs from GP1BB and ZAP70. Comparing OSCC vs normal healthy donors, these two genes revealed the highest discrimination power: ZAP70 showing hypermethylation and GP1BB showing hypomethylation. ROC analysis of all of the gene targets evaluated in this study is available in Additional file 3
