Bradford Hill viewpoints are among the most commonly used approaches for assessing causality in population health systematic reviews. Yet there is only limited guidance on their implementation, leading to considerable variation in how they are applied and reported. This seminar describes an example of how Bradford Hill viewpoints were used to assess causality in a systematic review on income inequality and health outcomes.

Michal will describe how the viewpoints incorporated counterfactual principles and how process tracing, a case study research method, was used to weigh evidence for each viewpoint. This structured approach offers practical guidance for improving transparency and rigour in causal assessment using Bradford Hill viewpoints within population health reviews.
