F2 and Hepatic fibrosis: The present results also demonstrate that M2BPGi levels correlated with platelets (p < 0.0001), PT (p < 0.05), albumin (p < 0.0001), ALT (p < 0.0001), and age (p < 0.0001) (data not shown), which were test items related to liver fibrosis, suggesting that the elevation in M2BPGi might be caused by the development of liver fibrosis consisting of both hemangioma-related fibrosis and age-related fibrosis.
