    Publication Bias in Meta-Analysis: Prevention, Assessment and Adjustments Hannah R. Rothstein, Alexander J. Sutton, Michael Borenstein Publication bias is the tendency to decide to publish a study based on the results of the study, rather than on the basis of its theoretical or methodological quality. Publication Bias in Meta-Analysis examines the different types of publication bias, and presents the methods for estimating and reducing publication bias, or eliminating it altogether. Written by leading experts, adopting a practical and multidisciplinary approach.

"Meta-analysis is now used in numerous scientific disciplines, summarizing quantitative evidence from multiple studies. If the literature being synthesised has been affected by publication bias, this in turn biases the meta-analytic results, potentially producing overstated conclusions.

In this example, an increase in risk is indicated by a risk ratio greater than The overwhelming majority of studies show an increased risk for second-hand smoke, and the last row in the spreadsheet Chapter Publication Bias.

The book includes a section with examples that show how to report the results of an analysis correctly. These examples can serve as templates for reporting an analysis, while avoiding the mistakes discussed in earlier chapters. The book’s author is the co-author of the text Introduction to Meta-Analysis, the best-selling text in this field.

Publication Bias in Meta-Analysis. Hannah Rothstein, Alex Sutton, Michael Borenstein Chichester: Wiley. Meta-Analysis provides a mathematically accurate synthesis of the available data, but cannot guarantee that the available data is unbiased. This is known as the publication bias problem and constitutes the topic of the book Publication bias in meta-analysis: Prevention, assessment and adjustments, edited by Rothstein, Sutton, and Borenstein ().This is the first book to address this issue in such detail and is likely to become a standard reference for those who carry out systematic literature by: Summary This Publication bias in meta-analysis book contains sections titled: Publication Bias As a Threat to Validity Organization of the Book Our Modest Proposal References Publication Bias in Meta‐Analysis - Publication Bias in Meta‐Analysis - Wiley Online LibraryCited by: Publication bias is the tendency to decide to publish a study based on the results of the study, rather than on the basis of its theoretical or methodological quality.

It can arise from selective publication of favorable results, or of statistically significant results. This threatens the validity of conclusions drawn from reviews of published scientific research. Meta-analysis is now used in. As such, the book introduces the key concepts and models used in meta-analysis.

It also includes chapters on the following advanced topics: publication bias and small study effects; missing data; multivariate meta-analysis, network meta-analysis; and meta-analysis of diagnostic by: In the multivariable analysis, assessment of publication bias was associated with SRs’ inclusion of a meta-analysis [odds ratio (OR) (95% CI)], reviewers reporting the use of SR Author: Philip Sedgwick.

Evidence of publication bias was found in meta-analyses published in prominent medical journals. Impact on meta-analysis. Where publication bias is present, published studies are no longer a representative sample of the available evidence.

This bias distorts the results of meta-analyses and systematic reviews. Meta-analysis is widely used as a method of summarizing and combining results from individual research studies. Heterogeneity and publication bias are two major problems in meta-analysis for binary data.

A latent meta-analysis model by using binomial distributions is proposed. This model allows for heterogeneity among different studies.

Perform fixed-effect and random-effects meta-analysis using the meta and metafor packages. Analyse the heterogeneity of your results. Tackle heterogeneity using subgroup analyses and meta-regression. Check if selective outcome reporting (publication bias) or p.

Introduction to Meta-Analysis () Michael Borenstein, Larry V. Hedges, Julian P.T. Higgins, Hannah Rothstein Chichester: Wiley This book provides a very clear overview of meta-analysis.

Publication bias is an inherent issue with meta-analysis, since studies (especially smaller ones) with “negative” results are frequently unpublished. Funnel plot, Begg and Mazumdar's rank correlation, and Egger regression are useful tools for assessing publication bias.

Chapter 9 Publication Bias. In the last chapters, we have showed you how to pool effects in meta-analysis, choose the right pooling model, assess the heterogeneity of your effect estimate, and determine sources of heterogeneity through outlier, influence, and subgroup analyses. Nevertheless, even the most thoroughly conducted meta-analysis can only work with the study.

Publication bias in meta analysis (AG) Combining data types in meta analysis (AG) We would especially like to take this opportunity to thank Dr Sidney M. Stahl. When publication bias is detected, an analyst can attempt to account for it[23,28,39,47,49–51].

Although the methods to conduct meta-analysis in the presence of a publication bias provide a powerful sensitivity analysis tool, their validity depends on the correctness of strong and unverifiable assumptions.
