Publication bias is defined as "the influence of study results on the chances of publication [in academic journals] and the tendency of investigators, reviewers, and editors to submit or accept manuscripts for publication based on the direction or strength of the study findings. Publication bias has an impact on the interpretation of clinical trials and meta-analyses. Bias can be minimized by insistence by editors on high-quality research, thorough literature reviews, acknowledgement of conflicts of interest, modification of peer review practices, etc."[1] Publication bias has been documented to occur[2].

Publication bias may be due to authors not submitting negative studies for publication.[3] This may especially be true of studies authored by industries with conflicts of interest.[4]

An example of probable publication bias is in the studies of glucosamine and chondroitin for treatment of osteoarthritis. In an initial meta-analysis, the authors noted evidence of publication bias during examination of the results.[5] A subsequent large randomized controlled trial[6] and meta-analyses including the large trial were negative[7][8].

Meta-analysis

Publication bias is a major threat to the validity of meta-analysis. Publication bias against negative studies may threaten the validity of meta-analyses that are positive and all the studies included within the meta-analysis are small.[9][10]
