Evidence maps

Driven by the latest machine learning software, we've mapped the published research of what works to address inequalities in and through primary care.

We use evidence mapping software and automation tools developed by the EPPI Centre at UCL to create Living Evidence Maps of published research on What Works to address health inequalities in primary care.

Building on our previous research looking at interventions to address inequalities in primary care, we have trained a machine learning algorithm to help us to efficiently identify further relevant studies to added to the maps. Studies included in the maps focus on primary care, inequalities and interventions, comprising umbrella reviews, systematic reviews, and primary studies published in academic journal articles. International studies are included, but only from high-income countries because they are most comparable to the NHS.

If we judge an article to be relevant, we apply a series of labels and they appear in the Evidence Maps below. We continually identify further relevant studies (articles) to be coded, so these maps are ‘Living’ and we publish updates of the maps every month.

Each map focuses on a key topic relating to health inequalities in primary care. The size of the circles in each map represents the number of research articles, and their colour represents the different types of research articles (for example systematic review or primary study).

The maps will never include every study published on a topic, but we hope they contain enough to inform decision-making. If you find an article that you think should be included, please let us know by contacting us here.
