A key assumption of Mendelian randomization (MR) analysis is that there is no association between the genetic variants used as instruments and the outcome other than through the exposure of interest. One way in which this assumption can be violated is through population stratification, which can introduce confounding of the relationship between the genetic variants and the outcome and so induce an

Investigators performing epidemiological research frequently form hypotheses based on data availability. One might ask how it could be otherwise. After all, what is the point of forming hypotheses if they can’t be tested? Read the paper at https://academic.oup.com/ije/article/50/4/1053/6259481

Project title: Early-life environmental risk factors for inflammatory bowel disease: A Nordic birth cohort study Project: Inflammatory bowel disease (IBD) is a chronic, debilitating immune-mediated disease with a typical onset in childhood and young adulthood. After a rising incidence over the past decades, it now affects 0.5% of Western populations, and is an emerging disease globally. There is a

Har du tappat bort ett USB-minne med känsliga uppgifter? Eller har du sett någon stryka omkring i universitetets lokaler med en möjlig avsikt att tillskansa sig värdefull information? Det finns gott om exempel på tänkbara informationssäkerhetsincidenter som måste anmälas. En informationssäkerhetsincident är ”en oönskad händelse med negativa konsekvenser som handlar om säkerheten för information".
