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
Purpose: Dry eye disease (DED) is a multifactorial chronic disorder of the ocular surface, characterized by reduced tear secretion, tear film instability, and inflammation. Oxidative stress is pivotal in DED pathogenesis. Qingxuan Runmu Yin (QRY) has shown substantial clinical efficacy in managing DED. This study aims to elucidate the molecular mechanisms underlying the antioxidant and anti-inflammatory effects of QRY in DED. Methods: A benzalkonium chloride (BAC)-induced DED mouse model was established to evaluate QRY's protective effects on the ocular surface. RNA sequencing identified differentially expressed genes (DEGs, fold change >1.5, P < 0.05) among control, untreated DED, and QRY-treated DED mice. Transcriptomic analysis of DEGs was conducted. The active ingredients and targets of the ten Chinese herbal medicines in QRY were obtained from the TCMSP and TCMIP databases, whereas DED and oxidative stress-related genes were identified from the DisGeNET, OMIM, and GeneCards databases. A Chinese herbal medicine-active ingredient-target-disease network was constructed. The key pathways and targets of QRY against DED were investigated through transcriptomics and network pharmacology, and experimental validation was performed. Results: QRY alleviated ocular surface damage in DED mice by repairing goblet cells, improving corneal damage, enhancing tear secretion, and reducing inflammatory factors and reactive oxygen species (ROS). Combined transcriptomic and network pharmacology analyses indicated that QRY reduced oxidative stress in DED by inhibiting pathways such as NF-κB and TNF. In vitro, QRY improved the survival of human corneal epithelial (HCE) cells damaged by oxidative stress. It inhibited the NF-κB signaling pathway and reduced levels of the pro‑inflammatory cytokines IL‑1β, IL‑6, and TNF‑α. In addition, QRY lowered ROS levels and enhanced superoxide dismutase (SOD) activity. Conclusion: This study is the first to demonstrate that QRY mitigates ocular surface inflammation and oxidative stress in DED, providing a scientific foundation for its clinical application.
