In this model the parameters Pro-C3, C4M, AST, and ALT were significantly associated with Metavir Fibrosis score (p<0.0001–0.026) resulting in an algorithm with the following equation: -0.72 x logALT + 1.69 x logAST + 3.81 x logProC3 + 1.53 x logC4M (r = 0.54; p<0.0001). Here, GPT is linked to fibrosis.
