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: The combination of Exocarpium Citri Grandis-Folium Ginkgo (E-GC) demonstrates superior therapeutic effects on liver injury caused by hyperlipidemia compared with individual use; however, accurate and quantifiable indicators for evaluating the efficacy and quality of the couplet remain lacking. Reliance solely on changes in certain differential metabolites or the bioavailability of chemical components is insufficient to confirm the superior efficacy of the couplet. Methods: In this study, a rat model of liver injury caused by hyperlipidemia was used to verify the enhanced efficacy of E-GC. Subsequently, network pharmacology combined with molecular biology validation was applied to identify the primary regulatory targets. The results were integrated with UPLC-TOF-MS, UPLC-MS and database analyses to identify biomarkers indicating the enhanced efficacy of E-GC, as well as serum concentrations of active components in E-GC to quantitatively evaluate the effect of the couplet on their bioavailability. Finally, correlation statistical analyses were conducted on the above-mentioned data to confirm that the identified biomarkers and significantly altered active components can characterize the enhanced efficacy of the couplet. Results: Metabolomics analysis identified 59 related metabolites, among which arachidonic acid, choline, deoxycholic acid, N-acetylserotonin, and cholic acid significantly increased in the liver following E-GC treatment, with similar changes observed in serum levels (p<0.05). A total of 36 components were identified, apigenin, naringin, and ginkgolide A/B/C exhibited significantly increased bioavailability after combination (p<0.05). These changes were closely associated with the improved regulation of PXR-FXR expression by E-GC compared with individual use, and E-GC also exerted strong regulatory effects on downstream targets, such as LXR, FGF1, ABCB1b, and ERK. Conclusion: Through the above analyses, in order to solve the problem of lacking accurate and quantifiable indexes to evaluate the effect of TCM couplet, a method was successfully established for evaluating the enhanced efficacy of E-GC in treating liver injury caused by hyperlipidemia, and the principal biomarkers and quality control indicators based on active components were identified.
