Beyond distance: integrating economic burden into large-scale primary healthcare accessibility analysis.
Article in Global health research and policy, 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
backgroundAccess to primary healthcare (PHC) services is a critical determinant of population health outcomes and a key indicator of health system performance. However, comprehensive methods for batch assessment of PHC accessibility and the associated economic burden are relatively scarce. This gap is particularly evident in developing countries, where accessibility challenges are often more pronounced.
methodsWe developed an integrated assessment methodology for the large-scale calculation of travel costs to access PHC services. This methodology combines high-resolution friction surface mapping, the construction of a comprehensive PHC facility spatial dataset, and the application of least-cost path algorithms. The batch processing capability of the methodology ensures efficient computation while maintaining high spatial resolution, enabling a detailed evaluation of PHC accessibility and its economic burden across diverse geographical contexts.
resultsOur analysis revealed that 88.70% of Chinese mainland's population could access PHC facilities within an hour, indicating relatively good overall accessibility to primary healthcare services. However, significant regional disparities in accessibility and associated economic burdens were observed. While urban areas, particularly in eastern and coastal regions, generally exhibit high levels of accessibility, rural and remote areas, especially in the western and northwestern regions, face substantial challenges in reaching PHC facilities. The total economic burden associated with travel to PHC facilities in Chinese mainland is estimated at approximately 38.29 billion CNY annually. The southern, northern, and northwestern regions accounted for 62.91%, 21.72%, and 14.94% of the total burden respectively, with northwestern provinces facing a disproportionately high economic burden relative to their GDP.
conclusionsOur methodology supports future large-scale, high-resolution accessibility analyses that can guide interventions aimed at addressing healthcare disparities and improving equity. The empirical application of this methodology in Chinese mainland revealed significant disparities in PHC access across the country and quantified the substantial economic costs associated with these disparities.
