The Clinical Outcome Research in Homeopathy database contains all types of clinical outcome studies, from randomised controlled trials to observational studies. At present it comprises clinical studies on homeopathy, published up to the start of 2018. This resource was the result of a close collaboration between HRI and Karl und Veronica Carstens Foundation in Germany.
