This paper introduces metapack, an R package simplifying complex meta-analysis and network meta-analysis. It offers flexible modeling and visualization tools for researchers, enhancing data synthesis and statistical inference.
Area of Science:
- Biostatistics
- Statistical Modeling
- Data Synthesis
Background:
- Meta-analysis is a statistical method for combining research findings.
- Aggregate data meta-analyses offer flexibility and are widely used.
- Complex statistical models hinder the adoption of advanced meta-analysis techniques.
Purpose of the Study:
- To introduce the R package metapack.
- To provide a unified formula interface for meta-analysis and network meta-analysis.
- To facilitate flexible variance-covariance modeling for multivariate and univariate network meta-analysis.
Main Methods:
- Development of the R package metapack.
- Implementation of a unified formula interface for meta-analysis and network meta-analysis.
- Inclusion of functions for plotting and statistical inference, including model assessment.
Main Results:
- The metapack package offers a user-friendly interface for complex meta-analysis models.
- Flexible variance-covariance modeling is supported for multivariate meta-analysis and univariate network meta-analysis.
- Demonstration of use cases with two real datasets included in the package.
Conclusions:
- Metapack simplifies the application of advanced meta-analysis and network meta-analysis techniques.
- The package enhances statistical inference and model assessment capabilities.
- Metapack promotes wider adoption of sophisticated meta-analysis methods in research.

The model approach uses mathematical models to describe changes in drug concentration over time. Pharmacokinetic models help characterize drug behavior in patients, predict drug concentration in the body fluids, calculate optimum dosage regimens, and evaluate the risk of toxicity. However, ensuring that the model fits the experimental data accurately...
