Table 2.

The 21 CpG sites for which receiver operating characteristic curve analysis showed area under the curve (AUC) values larger than 0.95 for discrimination of non-cancerous liver tissue samples showing non-alcoholic steatohepatitis (NASH) from partial hepatectomy specimens from patients with hepatocellular carcinoma (HCC) (NASH-W) from normal liver tissue samples (NLT), and larger than 85% specificity for discrimination of NASH-W samples from non-cancerous liver tissue samples showing NASH from biopsy specimens from patients with morbid obesity but without HCC (NASH-O)

cTSS1500 (from 200 bp upstream of the transcription start site [TSS] to 1500 bp upstream of it), TSS200 (from TSS to 200 bp upstream of it), 1st intron and gene body (2nd exon and downstream) were identified based on the RefSeq database (http://www.ncbi.nlm.nih.gov/refseq/)

dCpG islands, island shores (2000-bp regions adjacent to a CpG island) and island shelves (2000-bp regions adjacent to an island shore) were identified based on the University of California, Santa Cruz (UCSC) genome browser (https://genome.ucsc.edu/)

eNASH-W < NLT: the sample was predicted to be NASH-W and/or carcinogenic risk-positive when its DNA methylation level was lower than the cutoff value; NASH-W > NLT: the sample was predicted to be NASH-W and/or carcinogenic risk-positive when its DNA methylation level was higher than the cutoff value

fSpecificity was defined as the ratio of the number of tissue samples not diagnosed as NASH-W based on the criteria relative to the exact number of NASH-O samples. N/A, not annotated (designed in the intergenic regions)
