Selective outcome reporting is a major problem because it has a negative impact on our scientific knowledge and is unethical as it involves research on human subjects. And inadequate quality of trials may distort the results from systematic reviews and meta-analyses. Thus, Clinical medicine tries to solve the problem of trials by making public registration before patient enrollment mandatory and encouraging to report the research outcomes by a specific guidelines. In the past few years, the registration of clinical trials and the reporting system has become routine, supported by the International Committee of Medical Journal Editors. In Korea, the clinical research registry named 'Clinical Research Information Service (CRiS)' was recently established and became a data provider as a primary registry to the World Health Organization (WHO) International Clinical Trial Registry Platform search portal. To expand the registration system and to operate them successfully and comprehensively, active participations of researchers as well as the government supports are required.
