Identification of differentially expressed AS events in the three etiology groups. The total number of unique genes with identified AS events in three comparisons of HBV vs. HCV, HCV vs. alcohol, and HBV vs. alcohol were 143 (ΔPSI> 0.05) and 29 (ΔPSI> 0.1). a The numbers of unique gene exhibiting differential AS in the three comparisons (HBV vs. HCV, HBV vs. alcohol, and HCV vs. alcohol), were 55, 38, and 13, respectively. Moreover, 27, 6, and 3 genes were uniquely identified in the HBV, HCV, and alcohol groups, respectively. Only one gene was identified differentially in three different comparisons of each etiology group. b The numbers of unique differentially expressed AS genes observed for the three comparisons were 13, 3, and 4, respectively. Moreover, 7 and 2 genes were uniquely identified in the HBV and HCV groups, respectively. There was no gene differentially identified between each group comparison
