Editorial commentary
Non-author contributors should still be credited via acknowledgements, contribution statements, or explicit role declarations under CRediT-extension schemes. The category includes technical staff, research support personnel, data providers, and patient/citizen contributors. Reasons for non-authorship should be defensible against the criteria the work claims to follow (ICMJE, CRediT, etc.).
