VDR and Hepatic fibrosis: Figure 1 shows the prevalence of advanced liver fibrosis among patients with each VDR genotype. Chronic HCV patients with the FokI rs2228570 TT/TC genotypes (38.6%) were more likely to have advanced liver fibrosis compared to patients with the CC genotype (25.8%, p = 0.006). Pre-treatment HCV RNA level was not significantly different among patients who had different VDR genotypes, as shown in Fig. 2.
