Swedish cohorts with biobank samples are used today in many studies and have historically been of great importance for Sweden's scientific success in biobank research. There is no overall plan or strategy for it to continue in this way. The cohort working group within Biobank Sweden wants such a plan or strategy to be implemented. But how can that happen? In this second workshop, which is a continuation of previous work ("Are there wheels in the wheel of cohort research?"), we want to start a discussion with the aim of shaping a strategy for cohorts with sample collection. The invitation is addressed to those of you who work or do research in cohorts, preferably with sample collection. This event takes place in Swedish.
