Since open-access publication in 2015, it has been used by researchers and health professionals in 28 countries across 6 continents. The reach, spread, uptake and impact of NutComp are summarised, including indicators to support impact tracking for knowledge.Conclusion Given the complex phenomenon of research impact, careful planning is required to capture and attribute research impact.
