Problem:Question: Do known risk factors explain disparities in gallstone prevalence between Denmark and northeast Germany?
Answer: German individuals had a higher prevalence of gallstones than Danes. This difference was partly explained by a higher BMI, unfavorable lipid levels, higher prevalence of diabetes, and a more frequent use of OR and MHT in German subjects. Further research is needed to evaluate the impact of unmeasured predictors, including genetic components, on the population-related risk of gallstones.
Solution:
no
