All results, both positive and negative as well as inconclusive, will be sought published in international scientific peer-reviewed journals as well as presented on national and international scientific conferences. The Vancouver rules for authorship will be followed. There is a mutual agreement that Steffan Tábori Jensen will write the manuscript as the first author.
