Occupational characteristics are missing from heat vulnerability indices: a study in New York and New Jersey.
Article in Environmental health : a global access science source, 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
backgroundHeat vulnerability indices and maps are widely used by government agencies to guide heat-prevention strategies and prioritize resources for at-risk communities. However, these tools typically exclude the occupational characteristics of the population, a salient source of heat exposure.
methodsTo examine how occupation might enrich these tools, we developed a method to generate Census tract-level estimates of occupational heat exposure risk for employed residents using publicly available data from the U.S. Bureau of Labor Statistics Occupational Information Network (O*NET) and the U.S. Census American Community Survey Public Use Microdata Sample (2018–2022) and applied it to New York State (NYS) and New Jersey (NJ). We calculated the proportion of residents in occupations with elevated indoor or outdoor heat exposure. We then examined correlations and spatial alignment between occupational heat risk and social, health, and environmental vulnerability indicators.
resultsApproximately 1.3 million residents in NYS (13.6% of total employment) and 698,000 in NJ (15.1%) were employed in occupations with elevated indoor or outdoor heat exposure risk. Occupational heat exposure correlated most strongly with health vulnerability, followed by social vulnerability, while environmental vulnerability showed weak or negative correlations. Geographic overlap of tracts in the highest quintiles of occupational risk and other vulnerability domains was modest overall: occupational and health vulnerabilities aligned in less urban areas, whereas occupational, social, and environmental vulnerabilities clustered in and around urban centers.
conclusionsIntegrating occupation into climate and social vulnerability indices is important, because it is an essential human activity, a social determinant of health, and a salient source of heat exposure that is not fully captured by existing social, health, and environmental data. These findings provide a replicable method for mapping occupational heat exposure, highlighting populations at elevated risk, informing future research, and supporting targeted interventions in community and workplace settings, especially where enforceable workplace protections against extreme heat are limited.
