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
Purpose: Despite the growing role of Traditional Chinese Medicine (TCM) in China, little is known about the spatial accessibility and equity of TCM hospital resources at high geographic resolution. This study quantifies the spatial accessibility (SA) of TCM hospitals and assess the equity in resource distribution across Zhejiang Province to identify distributional disparities and inform policy responses. Methods: We applied a Two-Step Floating Catchment Area (2SFCA) framework augmented with navigation-derived travel times from a real-time route API to estimate SA for 99 public TCM hospitals and 25,601 residential demand points; equity was evaluated using Gini coefficients for four core resources (TCM physicians, TCM pharmacists, inpatient beds, and high-value TCM equipment), and spatial clustering was examined via Moran's I. Results: Among the 25,601 residential points analyzed, 93.47% were within a 60 min driving distance of a TCM hospital, covering 97.21% of the provincial population. However, accessibility varied considerably by municipality: Hangzhou exhibited the highest SA scores, while Lishui demonstrated consistently poor equity across all resource indicators. Gini coefficients ranged from 0.365 for TCM pharmacists (indicating proper equity) to 0.505 for medical equipment (indicating high inequity). Spatial autocorrelation analysis revealed distinct clustering patterns, with accessibility shaped by both topographical constraints and disparities in resource allocation. Conclusion: While Zhejiang achieves high overall SA to TCM hospitals, substantial inequities in resource allocation remain. Policy implications include targeted redistribution of high-value assets (for example, regional equipment-sharing consortia), deployment of mobile diagnostic and treatment units for remote and insular areas, incentives to attract TCM practitioners to underserved localities, and strengthening county-level service capacity to reduce intra-municipal disparities. These measures would help translate broad coverage into more equitable access to TCM services.
