Different epidemiological parameters have been suggested for the quanitification of the impact of an exposure factor on the burden of morbidity of a population, termed ``attributable risk''. Of these definitions, the ``AR'' as introduced by LEVIN (1953), including some transformations, is most commonly used. A structured search of the Medline(TM) database for publications dealing with this AR (1966 to 1996) identified 334 such original studies (mostly case control studies) and meta analyses, with a considerable increase during the last decade. Mostly, no precise reference was made to the definition of AR employed (64.5%). Adjustment procedures were performed in only 37.5% of studies, confidence intervals for point estimates of AR were calculated by only 19.3% of authors. Thus, in view of an encouraging popularity of this important public health parameter, the correct application of AR should be promoted further.
