Correlation between gene expression stability of nERGs and tERGs from qRT-PCR data and CV from each dataset.

M: average expression stability calculated by the geNorm program, S: stability value calculated by the NormFinder program. For 48 samples, 20 reference genes including 13 novel genes and 7 classical genes, were used in the correlation analysis. For 60 FFPE tissues, 19 reference genes excluding DIMT1L were included in the analysis.M值为geNorm程序（geNorm program）计算得到的平均表达稳定性，S值为NormFinder程序（NormFinder program）计算得到的稳定性值。针对48份样本，本次相关分析共纳入20个内参基因（reference genes），其中包含13个新发现基因与7个经典内参基因；针对60份福尔马林固定石蜡包埋（FFPE）组织样本，分析过程中纳入了剔除DIMT1L后的19个内参基因。
