The study shown on the slide used data from Britain and 12 other European countries to calculate age-standardized mortality rates for liver cirrhosis, and compared those results with trends in alcohol consumption.[1] In Britain, the rates of liver cirrhosis underwent a steady rise between 1950–2002.[1] In other European countries, the rates rose sharply up to a peak in the early 1970s, after which mortality rates reduced.[1] When compared with average alcohol consumption, the authors conclude that overall changes in alcohol consumption are accompanied by changes in the prevalence of liver cirrhosis.[1]
