COPE Forum 26 February 2018: Expressions of concern

How should journals use expressions of concern? They are “used to raise awareness to a possible problem in an article”. They are a relatively new, rare, and non-standardized type of editorial notice compared to corrections or retractions and “considerable differences in policy and practice remain between journals”. Journals are grappling with when expressions of concern are appropriate and what happens if the concerns are later found not to be valid.
