Spatial distribution and associated factors of public healthcare infrastructure in tourism-oriented environments: evidence from Southwest China in the context of residential tourism.
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: Public healthcare infrastructure is essential for ensuring equitable access to medical services, particularly in mountainous regions characterized by uneven development and tourism-oriented spatial environments. This study examines the spatial distribution of public healthcare infrastructure in Southwest China from a health geography perspective with particular attention to accessibility, spatial inequality and residential tourism contexts. Methods: A cross-sectional spatial analytical framework was applied to examine public healthcare infrastructure in Southwest China. Spatial analysis methods and the geographic detector model were employed to identify distribution patterns and associated factors. Residential tourism was operationalized through tourism-related spatial proxy variables rather than direct measures of tourist mobility or seasonal residence. Results: Public healthcare infrastructure exhibited a significant clustered distribution with high-density areas concentrated in Chengdu, Chongqing, Guiyang and Kunming and extensive low-density areas located in remote mountainous regions. Road network density showed the strongest explanatory power, followed by A-level scenic spot density and residential density. Interaction effects generally exceeded the explanatory power of individual variables with the interaction between road network density and A-level scenic spot density being the strongest. Traditional Village density showed negligible independent explanatory power. Conclusion: The distribution of public healthcare infrastructure in Southwest China reflects pronounced core-periphery inequality in facility concentration and the combined spatial associations of transportation connectivity, residential concentration, regional development and tourism-oriented environments. The findings extend the contextual application of health geography to residential tourism settings and provide a spatial screening basis for differentiated healthcare infrastructure planning. They should be interpreted as cross-sectional spatial associations rather than evidence of population mobility or seasonal healthcare demand.
