We examined, for the year 2009, the ethics requirements displayed on the website of 30 leading medical journals with an impact factor (IF) >10, and 30 others with an IF <10. We carried out a short study looking at the relationship between the IF of a journal and the ethics requirements in its instructions to authors. We show that the IF of a biomedical journal bears a direct relationship to its ethics requirements. Such results should improve the ethics requirements of all biomedical journals, especially those with low IF, so that they are internationally standardised to the higher standard required by journals with higher IF.
