As shown in Figure 6c, the univariate logistic regression analysis indicates that the three hub genes affect the occurrence of liver fibrosis, as follows: CDKN1A with an odds ratio (OR) of 1.22 (95% CI: 1.08–1.39), NR1I3 with an OR of 0.92 (95% CI: 0.87–0.89), and TUBB1 with an OR of 0.95 (95% CI: 0.80–1.16). This evidence concerns the gene CDKN1A and Hepatic fibrosis.
