Precise RANTES measurement in all 96 patients using a bead array confirmed this correlation (<italic>P</italic> = 0.002). However, the genetic RANTES haplotype was not significantly related to the serum level. The serum RANTES level was extracted by multivariate analysis (odds ratio = 4.09, 95% confidence interval = 1.02–16.5, <italic>P</italic> = 0.048) as an independent variable contributing to SVR.</p> </sec> <sec id="hepr12032-sec-0004" sec-type="section"> <title>Conclusion</title> <p>The serum RANTES level is an important determinant influencing the virological response to PEG IFN/RBV therapy in chronic hepatitis C.</p> </sec> </abstract>
