IJS developed Fig. Publication bias can be conceptualized as occurring in two stages: (I) from a study’s end to presentation of its results at a conference (and publication of an accompanying conference abstract) and (II) from publication of a conference abstract to subsequent “full publication” of the study results, typically in a peer-reviewed journal article [13]. Arguments against including conference abstracts are that (1) searching for abstracts is resource-intensive, (2) abstracts may not contain adequate information, and (3) the information in abstracts may not be dependable. Although these recommendations generally do not espouse including conference abstracts in systematic reviews, they provide excellent guidance on when including abstracts should be considered: • Reviewers should routinely consider conducting a search of conference abstracts and proceedings to identify unpublished or unidentified studies.

This would lead to a falsely inflated (or biased) estimate of the treatment effect of the intervention being evaluated in the systematic review. On the other hand, if the evidence does not show a sizeable effect, is imprecise, or is conflicting, then the resources spent finding and including conference abstracts may be worth it. JAMA. Dickersin K, Min YI, Meinert CL. However, in some cases, including conference abstracts has made a difference in the estimate of the treatment effect, not just its precision. J Clin Oncol.

From conference abstract to full paper: differences between data presented in conferences and journals. Cookies policy. When considering the use of conference abstracts in systematic reviews, we largely agree with the recommendations presented in the AHRQ Methods Guide for Comparative Effectiveness Reviews [1]. One aspect to consider is the scope of the review.

Cherry-picking by trialists and meta-analysts can drive conclusions about intervention efficacy. “Positive” results were associated with full publication, whether “positive” was defined as statistically significant results (risk ratio [RR] = 1.31, 95% CI 1.23 to 1.40) or as results whose direction favored the intervention (RR = 1.17, 95% CI 1.07 to 1.28). This finding suggests that the identification of an abstract without a corresponding full-length journal article should prompt systematic reviewers to search for additional evidence, such as gray literature sources and/or contacting the authors.

Benzies KM, Premji S, Hayden KA, Serrett K. State-of-the-evidence reviews: advantages and challenges of including grey literature. J Clin Epidemiol. Comparison of conference abstracts and full-text publications of randomized controlled trials presented at four consecutive World Congresses of Pain: reporting quality and agreement of results. In the context of publication bias arising during stage II (i.e., if abstracts with positive or significant results are selectively published in full), systematic reviews relying solely on fully published studies can be biased because positive results would be overrepresented.

These authors discussed four considerations for basing the decision to include conference abstracts: (1) complexity of the intervention, (2) consensus in the existing literature, (3) importance of context in evaluating the effect of the intervention, and (4) presence of other evidence [35]. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. EMBASE content: List of conferences covered in Embase. Third, the dependability of results presented in abstracts also is questionable [22,23,24], which occurs at least in part because (1) most abstracts are not peer-reviewed and (2) results reported in abstracts are often preliminary and/or based on limited analyses conducted in a rush to meet conference deadlines.

A meta-analysis of these 425 reports indicated that the overall full publication proportion was only 37% (95% confidence interval [CI], 35 to 39%) for abstracts of all types of studies and only 60% (95% CI, 52 to 67%) for abstracts of randomized controlled trials (RCTs). 1997;315:640–5. Ethics: This investigation analyzed only published conference abstracts and journal manuscripts, and therefore approval of the protocol by research ethics committee was not necessary. Washington, D. C: The National Academies Press; 2008. Those conducting systematic reviews have long grappled with this problem, known as “publication bias.” Publication bias occurs when either the likelihood of, or the time to, publication of a study is impacted by the direction of the study’s results [6,7,8,9,10,11,12].

From a systematic reviewer’s perspective, even if the unpublished abstracts were a random 3 in 10 abstracts, restricting a systematic review search to only the published literature would amount to the loss of an immense amount of information and a corresponding loss of precision in meta-analytic estimates of treatment effect. Thus, at best, approximately 3 in 10 abstracts describing RCTs have never been published in full, implying that the voluntary participation and risk-taking by multitudes of patients have not led to fully realized contributions to science. Follow-up of applications submitted to two institutional review boards. The most frequent scenario for publication bias is when studies with “positive” (or “significant”) results are selectively published, or are published sooner, than studies with either null or negative results. The committee generated a list of items from PRISMA and other sources of guidance and information … Other studies that have examined differences in treatment estimates of meta-analyses with and without conference abstracts report changes in precision, but usually not in the treatment effect estimate. 2013. PLoS One. Conference Abstract:: A Systematic Review of the Literature Analysis of APRN Roles Including Effectiveness of Clinical Nurse Specialist Role Second, largely driven by their brevity, abstracts may not contain adequate information for systematic reviewers to appraise the design, methods, risk of bias, outcomes, and results of studies reported in the abstracts [18,19,20,21]. When an external agency (eg, AHRQ) is engaged to develop the systematic review for an AAP guideline, the AAP will nominate the appropriate content experts and a key methodologist to serve on the AHRQ technical expert panel as well as to serve as key informants for AHRQ. As part of this effort, they compared abstracts with full-length journal articles and clinical study reports and reported that the information presented in abstracts was not dependable either in terms of methods or results. It is designed to be used in conjunction with the previous guidance for the reporting of an entire systematic review – the PRISMA statement.
