Research on the influence of spontaneous commercial space on the commercial vitality of historical and cultural districts.
Article in Scientific reports, 2025. 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
Spontaneous commercial spaces play a crucial role in shaping the vitality of historic districts, yet their spatial characteristics and impact on commercial activity remain understudied. This study employs Mask R-CNN deep learning, random forest regression analysis, and SHAP (Shapley Additive Explanations) to systematically identify and quantify the influence of spontaneous commercial spaces on commercial vitality. Based on a dataset comprising 4217 annotated images collected from Wuhan's Tanhualin Historic District, the study classifies spontaneous commercial spaces into five spatial types and examines their correlation with commercial vitality distribution. The results reveal that convex and scatter-occupying spontaneous spaces have the most significant positive impact, increasing commercial vitality by an average of 22.4% and 16.8%, respectively. SHAP analysis further highlights nonlinear interactions between crowd density and spatial typology, demonstrating that high-density areas amplify the contribution of convex spaces to vitality. Additionally, the spatial density of spontaneous commercial spaces shows a strong correlation with pedestrian flow intensity (R
