Summary

• What is new: The introduction of the CausalMetaR R package, providing methods for estimating causal effects using multi-source data with a focus on producing causally interpretable estimates for specific target populations.
• Why this is important: Traditional meta-analytic methods fail to produce causally interpretable estimates for well-defined target populations.
• What the research proposes: CausalMetaR offers efficient and robust methods for estimating average and subgroup treatment effects in target populations, using doubly robust and non-parametric estimators and incorporating data-adaptive methods.
• Results: The paper demonstrates the use of CausalMetaR through an example, showcasing its capability to produce efficient and robust estimates of causal effects.
