Burden of environmental heat and cold exposure and its attributable risk factors in 204 countries and territories (1990-2021).
Article in European journal of medical research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundEnvironmental heat and cold exposure poses significant public health challenges worldwide. Understanding the global, regional, and national burden of disease, as well as sociodemographic and risk factor associations, is essential for targeted interventions.
methodsThis secondary data analysis utilized age-standardized incidence rates (ASIR), mortality rates (ASMR), and Disability-Adjusted Life Years (DALYs) rates from the Global Burden of Disease Study 2021 to assess the health impacts of environmental heat and cold exposure globally from 1990 to 2021. Regional and national variations, as well as age, sex, and Socio-demographic Index (SDI) patterns, were analyzed. Health workforce density data from WHO were incorporated to examine associations with temperature-attributable burden.
resultsIn 2021, 3.4 million incident cases (ASIR: 45.1 per 100,000; 95% UI: 42.3-48.1) and 36,000 deaths (ASMR: 0.4 per 100,000; 95% UI: 0.3-0.5) were attributed to environmental heat and cold exposure worldwide, with 1.68 million DALYs (age-standardized rate: 20.4 per 100,000; 95% UI: 18.9-22.1). From 1990 to 2021, DALYs decreased by 53% (95% UI: 49-57%), highlighting global progress. However, disparities persist, with Central Asia and sub-Saharan Africa exhibiting the highest burden. Mongolia reported the highest national rates (ASIR: 366.4; ASMR: 5.2; DALY rate: 238.1 per 100,000). Men generally faced greater risks than women, particularly in older age groups. Cold exposure contributed 68% of total temperature-related DALYs, with opposing SDI gradients for heat (negative correlation) and cold (positive correlation) burden.
conclusionsWhile global reductions in temperature-attributable burden demonstrate progress, significant regional and national disparities persist, particularly in low-SDI regions. Effective healthcare policies, health workforce strengthening, and targeted interventions are critical to reducing the persistent burden in vulnerable areas.
