The study prospectively included 271 consecutive patients with CHB (n=95) or CHC (n=176) who had undergone liver biopsies. Each patient completed a
questionnaire on
smoking habits; anthropometric measurements and laboratory examinations were carried out and histological lesions were recorded. Results. In CHC patients, severe fibrosis was independently associated with a higher body mass index (BMI) (OR: 1.180, 95% CI: 1.028-1.354; p=0.019), heavy smoking (OR: 3.923, 95% CI: 1.356-11.348; p=0.
