Predicting geriatric environmental safety perception assessment using LightGBM and SHAP framework.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Global population aging highlights the need to understand how the elderly perceive safety in urban public spaces. This study used image semantic segmentation to identify key visual elements from panoramic images. A dataset was created by combining manual scoring with deep learning to explore how pocket park environments impact older adults' safety perceptions. Analyzing 497 images from 29 pocket parks in Xiamen Island with LightGBM and SHAP tools, researchers identified visual elements that significantly affect seniors' safety perceptions. The findings indicate: (1) Elderly environmental safety perceptions in the 29 surveyed parks on Xiamen Island were generally positive, yet safety scores varied markedly across parks. (2) Pedestrian area, car, wall, person, billboard, parterre, and vegetation were identified as the seven visual elements most impactful on elderly environmental safety perceptions. (3) Interactions among visual elements were observed, with vegetation exerting a notably regulatory effect on environmental safety perceptions, significantly enhancing the elderly's perception of security. This study's empirical analysis elucidates the influence of visual elements in pocket parks on elderly environmental safety perceptions, offering practical guidance for park planners to design more inclusive and secure green spaces for the elderly, with broad application potential.
