Activity	Example
Student involvement in WCEC research work to gain experience of research and knowledge mobilisation	4 Cardiff University (CU) medical students conducted COVID-19 related systematic reviews for the WCEC (pandemic impact on racism in the NHS, interventions to mitigate against racism in the NHS, pandemic impact on prison, and pandemic impact homeless populations. The students also presented findings at stakeholder meetings, at WG Evidence briefings and at public symposia. 3 CU students completed infographics to summarise the findings for three rapid reviews.
Identifying and sharing research gaps	All evidence reviews identified gaps where further research was needed. These gaps were highlighted in the Topline summary of each report. Gaps are being collated, and shared on the website as a resource for researchers and research funders.
Developing rapid review methodologies with research partner groups and sharing Centre methods.	Weekly meetings were held with research partners to develop the rapid review methodologies. All methods were shared e.g. with the UK health Security Agency, stakeholders and presented at Conferences. Our methods were described on the website, shared on request.
Sharing the questions on the WCEC work programme to raise awareness and avoid duplication	Shared on our website, and with the UK Health Security Agency Rapid Evidence Service, National Institute of Clinical Excellence (NICE) Wales, and COVID-END.
