The results of this study are significant in that they demonstrate a statistically significant impact of TGF-β1 polymorphism and levels on the incidence of hepatic cirrhosis and hepatitis C. The forest plots in Figures 3-4 present the statistical analysis of the impact of TGF-β1 polymorphism and levels on the incidence of the disease. Here, TGFB1 is linked to Cirrhosis.
