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: Medical resource distribution in China exhibits marked spatial disparities, with hospital bed allocation demonstrating particularly pronounced regional inequalities. These imbalances may significantly impact healthcare accessibility and population health outcomes across different provinces. Methods: This study employed a comprehensive analytical framework to examine hospital bed distribution across 31 provinces in China in 2022. We first conducted descriptive statistics and spatial autocorrelation analysis to identify distribution patterns. Subsequently, multiple linear regression (MLR) and spatial error model (SEM) were applied to evaluate the factors categorized into six dimensions: economic development, population structure, environmental conditions, education level, existing healthcare resources, and transportation infrastructure. Finally, the Geodetector method was systematically implemented to quantify individual factor contributions and their interaction effects based on spatial stratified heterogeneity principles. Results: Our analysis revealed three key findings: (1) Significant regional disparities existed in hospital beds per 1,000 population, with global spatial autocorrelation confirming strong clustering patterns. Local indicators of spatial association (LISA) identified high-high clusters in southwestern regions and low-low clusters in southeastern provinces; (2) Both MLR and SEM analyses indicated a negative correlation between sex ratio and bed availability, with SEM demonstrating superior goodness-of-fit by effectively addressing spatial autocorrelation; (3) Geodetector results showed GDP per capita served as the primary driver of bed distribution, revealing a threshold effect where bed demand concentrated in low-GDP regions. Notably, significant interaction effects that substantially magnified individual factor impacts, with the synergistic effect between disposable income per capita and sex ratio emerging as the most pronounced. Conclusion: This study reveals substantial spatial disparities in hospital bed distribution across China, highlighting the necessity of integrated regional policymaking that explicitly addresses multifactorial synergies to optimize equitable healthcare resource allocation.
