In the sensitivity analysis, performed on patients with advanced fibrosis (F4), we found the same differences in IP-10 and sCD163 between groups of patients, while there was no difference between HIV/HCV patients and HD in sCD14 and MMP-2 levels and between HIV/HCV and mHCV patients in MMP-2 levels (Figure 1). The gene discussed is MMP2; the disease is fibrosis.
