<p>Pretreatment plasma sCD26 concentrations (ng/mL) (<b>A</b>) and DPPIV activity (AU) (<b>B</b>) in patients from the DITTO-HCV study, and pretreatment plasma sCD26 concentrations (ng/mL) (<b>C</b>) in the TTG1 study grouped depending of treatment outcome. Box plots display the 10^th, 25^th, 50^th, 75^th, and 90^th percentiles. The dashed line indicates the 600 ng/mL sCD26 cut-off concentration. Statistics analysis using two-tailed Mann-Whitney U-test.
