From March 2024, studies from the CCMO-register on ToetsingOnline.nl are also visible in the Overview of Medical Research in the Netherlands (OMON). Following the earlier addition of the studies from the old National Trial Register (NTR), the addition of the studies from ToetsingOnline.nl is the second step in expanding the public research data on onderzoekmetmensen.nl. The studies will remain available at ToetsingOnline as well.
