Standard models in evidence synthesis work well in settings characterized by a large evidence base, the absence of effect modifiers, and connected networks. Handling sparse data, substantial between-study heterogeneity and disconnected studies, however, poses challenges to researchers and requires advanced methodology.
In the absence of head-to-head studies, evidence synthesis is a well-established technique to indirectly compare novel and established interventions in various disease areas. In standard settings, the most established methods for various outcome types work well and result in realistic effect estimates. However, there are a variety of situations when standard methods may no longer be sufficient:
- if there is only a sparse network of evidence
- if there is a large amount of between-study heterogeneity
- if the network is disconnected
