Medical insurance integration and spatial effects in China: evidence from quasi-natural experiments and linked administrative data.
Article in BMC health services research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe presence of spatial inequity among provinces in China has led to emerging challenges regarding the utilization and sustainability of health insurance within the framework of universal health coverage.
methodsThis study employed the gradual implementation of the medical insurance integration policy across 31 provinces in China as a quasi-natural experiment to investigate the spatial impact of this policy change on equity within the healthcare sector. The analysis utilized the analysis of linked administrative data and applied the Spatial Durbin Model to assess the impact of the policy change across provinces.
resultsThe findings revealed that policy integration influenced per capita benefits not only within the province where it was implemented but also extended its effects to neighboring provinces, demonstrating a general spatial siphon effect. Specifically, provinces with lower per capita benefits tended to gather with their neighbouring provinces with higher per capita benefits, and vice versa. DISCUSSION: This study provides empirical evidence for developing countries striving to enhance healthcare equity, highlighting its significance amid ongoing global discussions concerning spatial equity in medical insurance systems.
