Abstract	Background: Prior studies implying associations between receipt of commercial funding and positive (significant and/or pro-industry) research outcomes have analyzed only published papers, which is an insufficiently robust ap-proach for assessing publication bias. In this study, we tested the following hypotheses regarding orthopaedic manu-scripts submitted for review: (1) nonscientific variables, including receipt of commercial funding, affect the likelihood that a peer-reviewed submission will conclude with a report of a positive study outcome, and (2) positive outcomes and other, nonscientific variables are associated with acceptance for publication. Methods: All manuscripts about hip or knee arthroplasty that were submitted to The Journal of Bone and Joint Sur-gery, American Volume, over seventeen months were evaluated to determine the study design, quality, and outcome. Analyses were carried out to identify associations between scientific factors (sample size, study quality, and level of evidence) and study outcome as well as between non-scientific factors (funding source and country of origin) and study outcome. Analyses were also performed to determine whether outcome, scientific factors, or nonscientific vari-ables were associated with acceptance for publication. Results: Two hundred and nine manuscripts were reviewed. Commercial funding was not found to be associated with a positive study outcome (p = 0.668). Studies with a positive outcome were no more likely to be published than were those with a negative outcome (p = 0.410). Studies with a negative outcome were of higher quality (p = 0.003) and
