The UK HTA programme has released a guidance and resources for authors. It provides very specific requirements on reporting and refer very clearly to the use of appropriate guidelines, including CONSORT. CONSORT is highlighted as the guideline to use when reporting randomized clinical trials and a CONSORT checklist is required with submission of the final HTA report.
The guidance aims to help authors with the preparation of HTA reports commissioned by the HTA program, which are subsequently published in the journal Health Technology Assessment and available on the HTA website.
