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
Background: To curb the growth of medical expenses, the Chinese government has implemented the medical insurance payment reform based on Diagnosis-Related Groups (DRG). This study evaluates the impact of the DRG policy on hospitalization costs, length of stay, and 30-day readmission rates for patients with fractures and intervertebral disc herniation. Methods: Hospitalization settlement records for patients with fractures and intervertebral disc herniation from a tertiary hospital in a city in eastern China between 2016 and 2025 were selected. An Interrupted Time Series (ITS) analysis was employed, with January 2020 designated as the intervention point. Results: Following the implementation of the DRG policy, the total hospitalization costs accelerated from a monthly decrease of 0.12% to a monthly decrease of 1.03% ( Conclusion: DRG effectively controlled hospitalization and boosted TCM use without hurting quality. But length of stay kept falling with slower decline, especially in insured patients, showing heterogeneous effects. Policymakers should target payment types to improve equity and effectiveness. Sensitivity and placebo analyses further supported these findings.
