Fig. 2

Diagram representing main results of the associations found in the eligible publications. The visual aspect of the diagram, but not the rules for its construction, was based on the diagram built by Ashley EA et al., “Clinical assessment incorporating a personal genome” The Lancet 375(2010): 1525-35. Note: Font size of health outcomes and circle size of socioeconomic determinants are proportional to the number of eligible publications in which they featured. Black arrows represent strong evidence of an association between socioeconomic indicator and health outcome; grey arrows represent weak evidence and dashed arrows represent evidence of the “negative” associations. In the results obtained, “negative” includes migrant populations having better mental health and married individuals having higher prevalence of obesity. Evidence of all other associations had a “positive” direction, i.e., ill health was associated with lower education, lower income, female gender, unemployment, deprivation, having less differentiated occupations and living in an unfavourable or urban area.
