Interregional reimbursement reform in China lowers administrative barriers to healthcare utilization.
Article in Communications medicine, 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
backgroundGeographic segmentation of health insurance creates administrative barriers that limit patients' access to out-of-network healthcare, particularly in underserved regions. We assess the impact of a reimbursement reform removing interregional administrative barriers on patient healthcare utilization.
methodsWe conduct a quantitative quasi-experimental study using longitudinal administrative data from a representative city with limited high-tier medical resources. The causal effects of the reform are estimated based on patient visit records from January 2021 to November 2022 using a regression discontinuity of time (RDiT) design.
resultsThe reform significantly increases intercity healthcare visits by up to 11.2%, especially among low-income patients and women. While patients with severe conditions benefit, increased utilization for minor ailments also occurs. This surge in demand strains medical resources, leading to increased readmission rates without reducing hospital stays.
conclusionsRemoving administrative barriers enhances equity but may reduce healthcare efficiency if demand management is neglected. Policymakers should combine expanded access with investments in local healthcare capacity and demand-side controls to ensure sustainable and equitable service delivery.
