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

Urban center expansion represents a significant characteristic of modern urban development. However, this expansion does not necessarily enhance urban vitality directly, and may instead lead to vitality decline in traditional core areas. To analyze this spatial paradox, this study examines the spatial mismatch between urban center expansion and vitality loss in Guangzhou from 2013 to 2023, utilizing Dianping data and deep learning methods. The results show that from 2013 to 2018, Guangzhou’s urban center expansion mainly concentrates in peripheral areas with limited vitality loss, while from 2018 to 2023, the spatial mismatch between urban expansion and vitality loss significantly intensifies, particularly showing vitality decline in core areas. This phenomenon reveals a structural contradiction in current urban development - urban center expansion does not necessarily mean “the bigger, the better.” When promoting urban modernization, cities should balance development between inner and outer areas, diversify functions, and enhance social inclusiveness, with particular emphasis on supporting functional reconstruction and vitality revitalization in core areas to achieve sustainable urban development goals. This study not only provides new perspectives for understanding the relationship between urban center expansion and vitality loss, but also offers scientific foundations and policy recommendations for optimizing urban spatial structures and improving urban governance efficiency.
