Global dataset on heat wave exposure due to the urban heat island effect.
Article in Scientific data, 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
Continuing global warming and urbanization have increased the frequency and severity of extreme heat events in cities. Therefore, understanding how the urban heat island (UHI) effect influences cities is essential for developing effective mitigation and prevention strategies. A 1-km resolution dataset was constructed to assess heat-wave exposure attributable to UHIs in urban human settlements worldwide from 2003 to 2020. An adaptive urban-rural threshold method was employed to delineate the spatial extent of UHI impacts, and a spatiotemporally fitted MODIS surface temperature dataset was used to address missing data caused by cloud contamination. This dataset explicitly separates the contributions of background climate, local landscape characteristics, and urbanization to heat wave exposure, providing a scientific basis for identifying key UHI mitigation areas and developing heat wave risk early warning models that account for UHI effects. The proposed methodology and dataset support synergistic decision-making for integrating urban climate adaptation with sustainable development, and the technical framework can be extended to studies of UHIs and heat wave exposure in other regions worldwide.
