Impacts of Neighborhood Persistent Poverty and Socioeconomic Status on Hepatocellular Carcinoma Outcomes: A Large Population-Based Cohort Study.
Article in Cancer medicine, 2026. 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
backgroundHepatocellular carcinoma (HCC) survival in the United States varies sharply by neighborhood disadvantage.
aimTo determine whether residence in persistently impoverished or low-SES census tracts is independently associated with lower all-cause and HCC-specific survival.
methodsWe identified 51,323 adults with HCC using a population-based retrospective cohort from the Surveillance, Epidemiology, and End Results Research Plus Specialized Database (2006-2020). Two census tract-level socioeconomic exposures were defined: persistent poverty (≥ 20% living below the poverty line for approximately 30 years) and low SES (Yost Index first quintile). Overlap Propensity Score Weighting, combined with marginal structural models, estimated the 1-, 5-, 10-, and 15-year risks of all-cause and HCC-specific mortality.
resultsThe median follow-up was 16 months, 6058 (11.8%) lived in persistently impoverished tracts, and 9863 (19.5%) lived in low-SES tracts. After weighting, residents of persistently impoverished areas had a 1-year all-cause mortality risk of 46.0% vs. 40.3% (RD, 5.6%; 95% CI, 4.4% to 6.9%; RR, 1.14; 95% CI, 1.11 to 1.17) and an HCC-specific mortality risk of 33.3% vs. 28.6% (RD, 4.8%; 95% CI, 3.2% to 6.3%; RR, 1.17; 95% CI, 1.11 to 1.22). Living in low-SES tracts raised 1-year all-cause mortality risk to 32.5% vs. 30.1% (RD, 4.8%; 95% CI, 3.6% to 6.0%; RR, 1.12; 95% CI, 1.09 to 1.15) and HCC-specific mortality risk to 32.5% vs. 30.1% (RD, 2.5%; 95% CI, 1.4% to 3.5%; RR, 1.08; 95% CI, 1.05 to 1.12).
conclusionsBoth persistent neighborhood poverty and contemporary low SES independently contribute to significant increases in mortality risk after HCC diagnosis.
