Your contribution
to better science is an online registry for scientific studies involving animals conducted around the world. It is operated by the German Centre for the Protection of Laboratory Animals (Bf3R) at the German Federal Institute for Risk Assessment (BfR). The registry was launched as a reaction to the translational and reproducibility crisis and provides scientists a platform to register an exact study plan prior to the start of experiments in order to prevent selective reporting. This allows reviewers or other scientists to compare the initially registered contents with the final publication. Thereby, encourages transparency, reproducibility, and animal welfare.

Preregistration is recommended by multiple journals

Multiple journals already recommend preregistration in their editorial policies e.g. the journals of the nature portfolio or journals of the American Association of Cancer Research. Show your commitment to transparency and reproducibility by preregistering your study. Be one of the early adopters and mention your preregistration of your animal study in your cover letter and you will draw editor’s attention to your manuscript.
