"Analysis of baseline factors in HCV genotype 1 or 4 patients showed the following predictors to be significantly associated with viral clearance by week 12 (RVR or cEVR) by MLR: prescription of peginterferon alfa-2a (40KD) [vs Pegintron alfa-2b] (p<0.0001), lower HCV RNA level (p<0.0001), Asian vs Caucasian race (p=0.0490), Caucasian vs Black race (p=0.0057), Caucasian vs other race (p=0.0408), higher platelets (p<0.0001), absence of cirrhosis vs cirrhosis (p<0.0001), histology not assessed vs cirrhosis (p=0.0002), ALT quotient >3.0 (p=0.0004), younger age (p<0.0001) and lower body mass index (BMI) (p=0.0213) (Figure 3 below)."

All patients recorded as Asian were enrolled at sites in Europe, North and South America and North Africa
Genotype 1 and 4 patients without a histological diagnosis (i.e. not assessed) were typically more similar to patients with a confirmed diagnosis of no cirrhosis in terms of baseline age, diagnosis of steatosis, ALT ratio and platelet count ALT = alanine aminotransferase
