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
purposeTo examine the relationship between residential racial and economic segregation and main causes of death at the county level in the USA.
methodsResidential racial and economic segregation quintiles were determined using the Index of Concentration at the Extremes (ICE). Linear mixed-effects model was applied to calculate adjusted mortality rate ratios (aRR).
resultsThe ICE for race + income outperformed the ICE for race and the ICE for income. Among 3142 counties, the average age-adjusted all-cause mortality rates were 980.25, 919.82, 844.37, 781.82, and 703.01 per 100,000 across ICE for race + income quintiles, from the most deprived to the most privileged, respectively (p for trend: < 0.001). The corresponding aRRs for all-cause mortality were 1.32, 1.23, 1.17, 1.10, and 1 (p for trend: < 0.001). Furthermore, both mortality rates and aRRs for all 11 main causes of death showed a significant decrease from the most deprived to the most privileged counties (p for trend: < 0.001).
conclusionsThere is a strong association between residential racial and economic segregation and age-adjusted all-cause mortality as well as the 11 main causes of death in US counties, with a clear decreasing trend observed across ICE for race + income quintiles. These findings underscore the urgent need for policy interventions to reduce residential segregation, including equitable urban planning, investment in underserved communities, and improved access to healthcare and education in disadvantaged areas. Addressing these structural inequities could be an effective strategy for reducing mortality disparities and advancing health equity.
