Analysis Examples

The metafor package implements various meta-analytic models, methods, and techniques that have been described in the literature. The links below demonstrate how the models, methods, and techniques described in the respective articles/chapters can be applied via the metafor package. The articles are organized by topic (therefore, articles covering multiple topics may be listed multiple times). Alternatively, you can jump to the references at the bottom of the page for the list of articles in alphabetical order.

Fixed-, Random-, and Mixed-Effects Models

Multivariate/Multilevel Meta-Analysis Models

Meta-Analysis of Odds Ratios with the Conditional Logistic Model

Meta-Analysis of Odds Ratios with Peto's Method

Meta-Analysis of Proportions

Meta-Analysis of Incidence Rates and Rate Ratios

Meta-Analysis of 2×2 Tables and Person-Time Data using the Mantel-Haenszel Method

The use of the Mantel-Haenszel method for meta-analyzing risk differences, risk ratios, and odds ratios (for 2×2 table data) and for meta-analyzing incidence rate differences and incidence rate ratios (for two-group person-time data) is illustrated in the following article.

Effect Size Measures for Pretest Posttest Control Group Designs

The article below discusses the calculation of effect size measures for pretest posttest control group designs.

Heterogeneity Estimation in Meta-Analysis

Best Linear Unbiased Predictions

Meta-Analysis with Mixture Models
