GPT and hepatocellular carcinoma: Simvastatin reduced liver index when compared to the HCC group (p < 0.001) (Fig. 1b). Not only serum ALT was reduced by simvastatin by 0.6-fold when compared to the HCC group (p < 0.001) (Fig. 1d), but also lowered that of bilirubin, by 0.7-fold (p < 0.01) than that of HCC (Fig. 1e).
