Overview

XMETA is an R package that offers several functions for performing meta-analysis and visualizing outcomes. Through video tutorials, sample codes, and more, this website provides a comprehensive exploration of the features found in XMETA and how they may apply to your work.

X-META

There are existing R and STATA packages that perform several methods of meta-analysis, which may be supplemented by additional functions available in the XMETA R package.

What's new in XMETA?

The XMETA package is a comprehensive toolbox for meta-analysis that includes functions for:

• making inference for univariate and multivariate meta-analysis

• detecting and quantifying the evidence of small study effects (publication bias, heterogeneity)

• visualizing univariate and multivariate outcomes in meta-analysis

Existing R package 'meta':

• fixed effect and random effect meta- analysis (functions include metabin, metacont, metacor, and others)

• plots (forest, funnel, radial, etc.)

• statistical tests to evaluate bias (metabias, trimfill)

• meta-regression (metareg)

Existing STATA collection of commands:

• meta-analysis (metan, metaan, metacum)

• plots (metafunnel, confunnel)

• statistical tests to evaluate bias (metabias, metatrim)

• meta-regression (metareg)
