Clinical Trials

In line with requirements of the International Committee of Medical Journal Editors (http://www.icmje.org/, http://www.icmje.org/faq_clinical.html), Diabetologia requires authors to have registered their trial in an acceptable registry at the time of conception. The registry must:

• be accessible to the public at no charge
• be open to all prospective registrants and managed by a not-for-profit organisation
• be a mechanism to ensure the validity of the registration data
• be electronically searchable

Acceptable trial registries include:

• Australian New Zealand Clinical Trials Registry (www.actr.org.au)
• ClinicalTrials.gov (www.clinicaltrials.gov)
• International Standard Randomised Controlled Trial Number Register (http://isrctn.org)
• UMIN Clinical Trials Registry (www.umin.ac.jp/ctr/index.htm)
• Nederlands Trial Register (www.trialregister.nl/)
• or any registries accepted by WHO as primary registers (see www.who.int/ictrp/network/primary/en/index.html)

The trial registry number should be included at the end of the Abstract.

Randomised control trials Authors should follow the CONSORT statement (see http://www.consort-statement.org/index.aspx?o=1011) and also include a patient flow diagram.
