Publication Delay of Systematic Reviews in Dentistry: Findings, Implications, and Potential Solutions

Clinicians, researchers, and policymakers often rely on the available scientific evidence to make strategic decisions. Systematic reviews (SRs) occupy an influential position in the hierarchy of scientific evidence. The findings of wellconducted SRs may provide valuable information to answer specific research questions1,2 and identify existing gaps for future research.3 Therefore, it is of supreme importance that SRs are published promptly, reducing as much as possible the time elapsed between the last date of the search for primary studies and the actual publication date. A study published in 2014 assessed the publication delay of SRs in orthodontics, revealing that the median time interval from the last search to publication was more than 1 year (13.2 months).4 Delays in the publication of SRs or original research articles may depend on author-related factors (eg, timing of resubmission after receiving feedback from reviewers) or journal-related factors (eg, time taken to process a submission).5-7 Regardless of the reasons, clinical recommendations and translation of SR findings may be affected by publication delay. We assessed the extent of publication delay of systematic reviews in dentistry with the purpose of addressing its implications and presenting potential solutions.
