INS and metabolic dysfunction-associated steatohepatitis: In an effort to decipher the clinical significance, we tested the correlations of DNA methylation of the three groups of CpGs (Only-NASH, NASH-SFA, and only-SFA) with the laboratory measurements reflecting lipid and glucose metabolism: serum lipids, serum insulin, and plasma glucose levels (represented as a heatmap in Additional file 2: Fig. S1; adjusted p value < 0.1 tabulated in Additional file 6: Table S3).
