How much alcohol is in a standard drink?
A group of researchers have undertaken a review of 125 international, published, epidemiological studies that relate various physical harms to different levels of alcohol consumption. For this review it was necessary to be able to compare the data from the different studies directly. The different measures of alcohol quoted in the studies were converted to the standard measure of grammes of alcohol. The present paper discusses the problems involved in doing this, and gives details of the conversion methods used.
