The second way to add value in research is to ensure that new research is appropriately designed to reduce potential bias, and is based on what is already known.
We do this through robust and transparent peer and expert review and by ensuring that all new primary research is set in the context of a review of existing knowledge. By seeking all available evidence for a given topic, the appropriate and timely conduct of a systematic review can help researchers and the NIHR design new primary research, or see whether a new study is actually needed.
