Fredrik Nyberg, visiting professor of register epidemiology, has recently started a seminar series on register research. In the first seminar, he gives an overview of how register research is done. He talks about the research process from ear to loaf – idea, ethics, data ordering, analysis and results. Until March 1, you who missed the seminar can see a recording. The next seminar in the series will be given on February 25, when Ola Rolfson and Erik Bülow from the Department of Orthopedics will talk about what is a clinically important difference in register-based research. Note – the seminars are held in Swedish.
