Reporting experiments in homeopathic basic research (REHBaR)--a detailed guideline for authors.
BACKGROUND
Reporting experiments in basic research in homeopathy is an important issue as comprehensive description of what exactly was done is required. So far, there is no guideline for authors available, unlike criteria catalogues common in clinical research.


METHODS
A Delphi Process was conducted, including a total of five rounds, three rounds of adjusting and phrasing plus two consensus conferences. European researchers who published experimental work within the last five years were involved.


RESULTS
A checklist of 23 items was obtained and supplemented with detailed examples emphasizing what each item implies. Background, objectives and possible hypotheses should be given in the part 'introduction'. Special emphasis is put on the 'materials and methods' section, where a detailed description of chosen controls, object of investigation, experimental setup, replication, parameters, intervention, allocation, blinding, and statistical methods is required. The section 'results' should present sufficient details on analysed data, descriptive as well as inferential. Authors should discuss their results and give an interpretation in the context of current evidence.


CONCLUSIONS
A guideline for Reporting Experiments in Homeopathic Basic Research (REHBaR) was compiled to be applied by authors when preparing their manuscripts, and to be used by scientific journals in the reviewing process. Furthermore the guideline is a commitment to a certain minimum quality level needed in basic research, e.g. blinding and randomisation. Feedback is encouraged on applicability, strength and limitations of the list to enable future revisions.
