Identification of retracted publications and completeness of retraction notices in public health J. Clin. Epidemiol. (IF 7.3) Pub Date : 2024-06-14 Caitlin J. Bakker, Erin E. Reardon, Sarah Jane Brown, Nicole Theis-Mahon, Sara Schroter, Lex Bouter, Maurice P. Zeegers
Retraction is intended to be a mechanism to correct the published body of knowledge when necessary due to fraudulent, fatally flawed, or ethically unacceptable publications. However, the success of this mechanism requires that retracted publications be consistently identified as such and that retraction notices contain sufficient information to understand what is being retracted and why. Our study
