Environmental determinants of hiking, jogging, and cycling along the Beijing-Tianjin-Hebei grand canal: implications for health promotion.
Article in Frontiers in public health, 2026. 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
Introduction: The Grand Canal in the Beijing-Tianjin-Hebei offers abundant ecological resources and socio-economic value that can support physical activity and social interaction, yet its use remains largely spontaneous and underutilized for regional health promotion. Methods: This study quantifies how canal-adjacent space promotes hiking, jogging, and cycling, identifies correlating features and spatial heterogeneity, and proposes optimization recommendations. Using participant movement trajectories, we combine XGBoost with multiscale geographically weighted regression to assess factor importance and spatial nonlinearity. K-Means clustering classifies canal-adjacent areas into ecology (52.9%), service (29.5%), living (11.7%), and mixed (5.9%) types; Natural Breaks delineates advantage zones for physical activity. Results: Promotion indices derived from factor weight coefficients quantifies conversion efficiency across spatial types. Illumination intensity and population density correlate strongly with three activity types. Hiking is mainly driven by slope gradient, accessibility to fitness facilities, and NDVI; jogging correlates with office complex, canopy height, and distance to bus station; cycling depends mostly on natural features. Discussion: Effects are generally nonlinear and spatially heterogeneous, centering on the Beijing-Tianjin segment with decreasing influence toward the periphery. In addition, comparing the four spatial types, mixed spaces show the highest conversion efficiency. We propose targeted development strategies and a progressive spatial enhancement model to strengthen sports functions.
