Probability of fibrosis progression-free survival by iron and HCV status after controlling for confounding variables.

Patients were stratified into 6 groups according to hepatic iron concentration and HCV status. HCV-negative patients with low and medium hepatic iron levels did not show progression of fibrosis and were grouped together: HCV-negative and low-medium iron (0.5-12.7 mg/g dw), n = 62; HCV-positive and low iron (0.5-5.6 mg/g dw), n = 32; HCV-positive and medium iron (5.7-12.7 mg/g dw), n = 43; HCV-negative and high iron (12.8-40.6 mg/g dw), n = 27; HCV-positive and high iron (12.8-40.6 mg/g dw), n = 37.
