The design‐by‐treatment interaction model: a unifying framework for modelling loop inconsistency in network meta‐analysis

Journal Article

In this note, we clarify and prove the claim made Higgins et al. () that the design‐by‐treatment interaction model contains all possible loop inconsistency models. This claim provides a strong argument for using the design‐by‐treatment interaction model to describe loop inconsistencies in network meta‐analysis. © 2015 The Authors.
