  author={Morgan C. Wang and Brad J. Bushman},
  journal={Psychological Methods},
In a meta-analysis, graphical displays can be used to check statistical assumptions for numerical procedures and they can be used to discover important patterns in the data. The authors propose the normal quantile plot as a preferred alternative to the funnel plot for such purposes. The normal quantile plot, like the funnel plot, can be used to investigate whether all studies come from a single population and to search for publication bias. However, the normal quantile plot is easier to… Expand
More than numbers: the power of graphs in meta-analysis.
Ratings of the forest plot and the standardized residual histogram were best associated with parameter heterogeneity, and meta-analysts should be selective in the graphs they choose for the exploration of their data. Expand
Evaluation of the Normality Assumption in Meta-analyses.
This work presents a standardization framework for evaluation of the normality assumption and examines its performance in random-effects meta-analyses with simulation studies and real examples and illustrates the real-world significance of examining thenormality assumption with examples. Expand
Graphical displays for meta-analysis: An overview with suggestions for practice.
This work reviews standard and proposed graphical displays for presentation of meta-analytic data, and offers recommendations on how they might be presented to provide the most useful and user-friendly illustrations. Expand
Outlier and influence diagnostics for meta-analysis.
Standard diagnostic procedures developed for linear regression analyses are extended to the meta-analytic fixed- and random/mixed-effects models to illustrate the usefulness of these procedures in various research settings. Expand
Publication bias in research synthesis: sensitivity analysis using a priori weight functions.
A new approach is proposed that is suitable for application to meta-analytic data sets that are too small for the application of existing methods and estimates parameters relevant to fixed-effects, mixed-effects or random-effects meta-analysis contingent on a hypothetical pattern of bias that is fixed independently of the data.

Methods for detecting, quantifying, and adjusting for dissemination bias in meta-analysis are described.
An overview of existing methods to detect, quantify, or adjust for dissemination bias is presented and it remains difficult to advise which method should be used as they are all limited and their validity has rarely been assessed. Expand
Conducting Meta-Analyses in R with the metafor Package
The metafor package provides functions for conducting meta-analyses in R. The package includes functions for fitting the meta-analytic fixed- and random-effects models and allows for the inclusion ofExpand
Charting the landscape of graphical displays for meta-analysis and systematic reviews: a comprehensive review, taxonomy, and feature analysis
A comprehensive overview of available graphs allows researchers to make better-informed decisions on which graphs suit their needs and therefore facilitates using the meta-analytic tool kit of graphs to its full potential. Expand
Meta-analysis of genetic association studies.
It is shown that meta-analysis has been successful in revealing unexpected sources of heterogeneity, such as publication bias, and can confirm the involvement of a genetic variant, but it is not a substitute for an adequately powered primary study. Expand
Meta-analysis in ecology
How difficulties resulting from missing data, publication bias, data quality and data exclusion, non-independence among observations, and the combination of dissimilar data sets may affect the perceived utility of meta-analysis in these fields and the soundness of conclusions drawn from its application is examined.

Graphical Methods for Data Analysis
This paper presents a meta-modelling framework for developing and assessing regression models for multivariate and multi-dimensional data distributions and describes the distribution of a set of data. Expand
Consequences of Prejudice Against the Null Hypothesis
The consequences of prejudice against accepting the null hypothesis were examined through (a) a mathematical model intended to stimulate the research-publication process and (b) case studies ofExpand
The file drawer problem and tolerance for null results
Quantitative procedures for computing the tolerance for filed and future null results are reported and illustrated, and the implications are discussed. Expand
A Meta‐Analytic Analysis of Effects of Psychoeducational Interventions on Length of Postsurgical Hospital Stay
The belief that brief psychoeducational interventions may be cost effective with surgical patients of many kinds because the length of hospital stay is reduced is supported. Expand
Gender differences in aggression as a function of provocation: a meta-analysis.
The results support a social role analysis of gender differences in aggression and counter A. H. Eagly and V. Steffen's (1986) meta-analytically inability to confirm an attenuating effect of provocation on gender Differences in aggression. Expand
