We expect a degree of duplicate registration. Registration information can be posted or faxed to the editorial offices of the Croatian Medical Journal. The information will be made available by listing the trial details on a web site, and in other ways as appropriate. If specific trial data are required, for example by those conducting systematic reviews, then the reviewer will be able to seek this information directly from the trialist. Some of the trials may be suitable for full publication, and the journal will be happy to consider these.
Medical editors are acutely aware of the trials and tribulations of research reporting.
But on this occasion, because of the serious implications of unreported research, we are endeavoring to cleave the trials from the tribulations. We cannot confidently estimate the total number of unreported trials, but we are confident of a good response. NIH clinical trials and publication bias.
