Acknowledgements We would like to thank all those who have contributed, under anonymity, to the evidence base. Without these rich responses we could not have created such a community inspired document. The credit framework we use is the Contributor Roles Taxonomy CRediT – a high-level taxonomy comprising 14 roles that can be used to describe contributions to a research output. While the contributor roles definition can be open to interpretation, we consider that they fit well the types of contributions we have attributed to the authors.
