1 · What the graph read from it

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.

2 · The registry

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

Investigating the urban heat island (UHI) effect across different seasons can reveal the impact of seasonal temperature changes on the urban environment, improve the living standard, and develop feasible measures to mitigate UHI effects. In the study, the land surface temperature (LST) of summer and winter was quantitatively retrieved in a megacity (Shenzhen city) during 2013-2023. Through the standard deviation ellipse, profile analysis and the GeoDetector model, this study systematically analyzed the spatial-temporal evolution characteristics and driving factors of the urban thermal environment in summer and winter. The results showed that summer LST initially decreased and then increased from 2013 to 2023, while winter LST consistently increased. During the study, the summer UHI area decreased, whereas the winter UHI area increased. The LST of green land, wetland, and natural open water were lower than that of cropland, unvegetated land and artificial surface, demonstrating that water and vegetation had a mitigating effect on UHI. Land cover type interactions with normalized difference built-up index (summer) and PM2.5 (winter) have the most significant influence on UHI. This study could provide scientific references for rational urban planning and sustainable urban development.
