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: This study aims to investigate the potential targets and signaling pathways of fenugreek, a key component of Hanchuan Zupa Granule, in treating COPD using network pharmacology and single-cell RNA sequencing. Patients and Methods: Utilizing single-cell RNA sequencing data on lung tissues from COPD patients (GSE173896 dataset) and network pharmacology, we analyzed alterations in cell populations, pseudotime trajectory of alveolar macrophages, intercellular communication networks, and performed functional enrichment and molecular docking of active fenugreek compounds with disease-related targets. Key bioinformatics tools and databases included Seurat, Monocle2, CellChat, Cytoscape, AutoDock Vina, PyMOL, TCMSP, SwissTargetPrediction, and Comparative Toxicogenomics Database. Results: A total of 39,240 high-quality single cells were obtained from COPD patients, leading to the identification of 23 distinct cell clusters, including 13 major immune and epithelial cell types. Notably, the proportion of senescent alveolar macrophages was significantly higher in COPD samples compared to controls, indicating enhanced involvement in inflammation and oxidative stress (P < 0.05). Pseudotime trajectory analysis categorized nine alveolar macrophage subtypes, demonstrating distinct differentiation pathways concerning inflammation, tissue repair, and cellular senescence. Network pharmacology identified 148 overlapping genes between the targets of fenugreek and COPD, with functional enrichment analyses revealing significant associations with "cytokine-mediated signaling" and "oxidative stress response." Molecular docking indicated that bioactive compounds of fenugreek exhibited strong binding affinities to CCL2 and IL1R1, confirming their roles in disrupting inflammatory signalling and limiting oxidative damage. Conclusion: Our integrated analysis suggests that fenugreek in Hanchuan Zupa Granule holds promise as a therapeutic strategy for modulating inflammatory and oxidative pathways in COPD and provides a strong mechanistic hypothesis centered on the IL1R1/CCL2 axis for experimental validation.
