Classes of daily alcohol consumption of the screened population (n=6534), expressed as absolute number (n) and percentage of lines (%), according to the presence of either non-cirrhotic alcohol-induced liver damage (NCLD) or cirrhosis or hepatocellular carcinoma (=cirrhosis)

Anti-HCV and HbsAg positive subjects (n=313), and 70 subjects in whom either the food questionnaire or the blood tests were not completed were also excluded.
aIn order to calculate odds ratio and 95% confidence intervals (CI), all the groups that showed statistical significance for the presence of either NCLD or cirrhosis at the multivariate analysis (that is, people drinking more than 30 g/day) were compared with the teetotallers and the moderate drinkers (<30 g/day) grouped together. Above this threshold limit p was always less than 0.00001.
bp v teetotallers, not significant.
