The `multinma`

package implements network meta-analysis, network meta-regression, and multilevel network meta-regression models which combine evidence from a network of studies and treatments using either aggregate data or individual patient data from each study (Phillippo et al. 2020; Phillippo 2019). Models are estimated in a Bayesian framework using Stan (Carpenter et al. 2017).

You can install the released version of `multinma`

from CRAN with:

And the development version from GitHub with:

Installing from source (either from CRAN or GitHub) requires that the `rstan`

package is installed and configured. See the installation guide here.

A good place to start is with the package vignettes which walk through example analyses, see `vignette("vignette_overview")`

for an overview. The series of NICE Technical Support Documents on evidence synthesis gives a detailed introduction to network meta-analysis:

Multilevel network meta-regression is set out in the following methods paper:
