  1. Notes
  2. a = journal recommends use of the procedure; ✗ = journal does not recommend use of the procedure. Rows 1–13 are JCR Q1 journals and rows 14–33 are Q2 journals.
  3. b Three journals (Food Policy, Appetite and Journal of Functional Foods) contained a link to their publisher which stated that it supported clinical trial registration for relevant journals. These were rated ✗ (No) in the table as the language in linked document is vague and does not state which journals are relevant.
  4. c Procedure mentioned only in a document linked to the instructions for authors, but not in the actual instructions.
  5. d One set of guidelines mentioned in the instructions for authors (ARRIVE) and one (CONSORT) mentioned only in a document inked to these.
  6. e Three sets of guidelines are mentioned in the instructions for authors (PRISMA; CONSORT; ARRIVE), and these and one other (TOP) are mentioned in a document linked to instructions.
  7. f One set of guidelines mentioned in the instructions for authors (CONSORT) and two (CONSORT; ARRIVE) mentioned in a document linked to these.
  8. g One set of guidelines mentioned in the instructions for authors (ARRIVE) and two (CONSORT; ARRIVE) mentioned in a document linked these.
  9. h Two sets of guidelines mentioned in the instructions for authors (the EQUATOR Network and PRISMA) and one (ARRIVE) mentioned in a document linked to these.
  10. i 22 of the 25 journals encourage data sharing for all types of studies. Additionally, Obesity and Applied Physiology Nutrition and Metabolism each requires a written data sharing statement for clinical trials, but not for papers reporting other study designs. Only Nutrition and Diabetes requires data sharing as a condition of publication.
