COMCEPT – The Portuguese Skeptics Community: As a volunteer-run and grass-roots organization aiming to promote rationality and critical thinking, COMCEPT – The Portuguese Skeptics Community fully supports the All Trials campaign. It is our understanding that, only with full disclosure of clinical trials data, will doctors, health professionals, and patients be able to make informed, rational, and scientifically-based decisions about health care. The disclosure of all the trials’ results will improve our true knowledge about the evidence behind each treatment and thus contribute to further advance science based medicine.
