A study in which the investigators do not seek to intervene, but simply observe the course of events. There is a greater risk of selection bias than in experimental studies.
Outcome
A component of a participant's clinical and functional status after an intervention has been applied, that is used to assess the effectiveness of an intervention.
Output
Published results from a research project. NIHR projects often generate papers that are published in the scientific literature. Full details of NIHR projects and their results are published in special reports or journals. Some projects generate briefing papers or other outputs for particular audiences.
