HCV = hepatitis C virus; ND = intrinsic clearance of 18F-FDGal could not be determined (7); mean ± SE = weighted mean ± SE of weighted mean.
Vmax and Km were calculated according to Equation 2; LC was calculated according to Equation 1. Individual data are given as mean ± SE of estimate. Data from healthy subjects are from Sørensen et al. (3).
