Trends in neighbourhood socioeconomic disadvantage and mortality disparities over three decades in Denmark.
Article in Journal of epidemiology and community health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNegative associations between neighbourhood socioeconomic disadvantage and health are well documented. However, limited longitudinal evidence exists on the dynamic nature of the neighbourhood context and implications for health disparities. Using rich register data, we examined how neighbourhood disadvantage in Denmark changed over three decades and explored associations with mortality rates.
methodsThis ecological study used nationwide register data from 1987 to 2018. A neighbourhood socioeconomic disadvantage index was created using aggregated data on neighbourhood-level educational attainment, unemployment and family income. Trends in the neighbourhood index were assessed using descriptive and geospatial analyses. Associations with age-standardised mortality rates were plotted and examined in regression-based models.
resultsNeighbourhood socioeconomic conditions generally improved over the three decades, and the mean difference between disadvantaged quartiles narrowed. The location of the most and least disadvantaged quartiles was largely stable across the period. Mortality rates generally decreased over time; however, rates of decline differed, leading to increased mortality disparities by quartile of neighbourhood disadvantage. Regression analysis demonstrated an increase in the association between neighbourhood disadvantage and mortality rates over time. First-difference regression models showed no association between change in neighbourhood disadvantage and change in mortality rates.
conclusionsDespite general improvements in neighbourhood socioeconomic conditions and neighbourhood mortality rates across the last three decades in Denmark, we found growing health inequality between more and less disadvantaged neighbourhoods. A strong concentration of disadvantage over time and space and growing segregation of income levels may have contributed to this development, with important implications for public policy and health policy investments.
