All research papers need checking carefully – yes, even yours! A well edited paper will take a journal editor or peer reviewer less time to assess and may be more likely to be accepted.

As expert editors, we can spot possible improvements to your paper that you won’t have thought of. So we can improve your paper even if you are a good writer.

Editing by Cofactor is not intended to replace peer review. Rather, we aim to flag up potential problems that might confuse or annoy peer reviewers, journal editors and readers.

Editing includes checking and correcting where possible for:


  • nothing crucial has been missed out
  • figures and tables are clear and consistent
  • all cited references are listed in the reference list and vice versa
  • the target journal’s style is followed if relevant
  • all abbreviations and technical terms are defined


  • the text is clear and unambiguous
  • the grammar, spelling and punctuation are correct
  • the writing style fits the intended audience
  • there is no potentially offensive or inappropriate language


  • the claims made appear to be supported by the evidence provided
  • statistical tests are included where they appear to be necessary
  • applicable standards are adhered to (such as CONSORT for randomised controlled trials)
  • conventions such as capitalisation of gene and protein names are adhered to
