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

Rapid urban developments have resulted in numerous environmental challenges, including severe air quality and heat island effect problems. The construction of urban ventilation corridors provides an effective solution for enhancing air circulation and reducing the heat island effect. The present study focuses on Nanhu District, Jiaxing City, Zhejiang Province, employing Unmanned Aerial Vehicle tilt photography to obtain high-resolution urban remote sensing data and create a three-dimensional digital model of the city. Wind direction and speed over the past decade were analyzed in the proposed study area. Dominant wind directions were identified for both summer and winter seasons to calculate frontal area density under dominant wind directions, while an area growth method was applied with limited direction to determine urban ventilation corridors. The experimental results show two ventilation corridors under the winter-dominant wind direction and four under the summer-dominant wind direction. The results were validated against fieldwork conducted by three urban planning experts, with an error rate of 4.91% and 4.57% on a digital map. Eventually, this study will provide a tangible scientific foundation and technical support for the planning and construction of urban ventilation corridors to mitigate the heat island effect and improve air quality.
