Estimating alcohol-attributable fractions for injuries based on data from emergency department and observational studies: a comparison of two methods.

Two methods of estimating the injury alcohol-attributable fractions-emergency department data versus population method-produce widely differing results. Across 36 country-years, the mean AAF using the population method was 36.8%, more than twice as large as emergency department data-based acute estimates, which average 15.4%.
