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
Objective: To explore the effects of Methods: In vitro, the human TNBC cell lines were treated with the extract at various concentrations. Cell viability was assessed using the CCK8 assay. In vivo, establishing a subcutaneous xenograft tumor model of TNBC, Hematoxylin-eosin staining and TUNEL assay were used to evaluate the effect of CnE on tumor proliferation. Tumor proteins were extracted, Quantitative proteomics and subsequently analyzed using bioinformatics approaches. Finally, immunohistochemistry evaluates the protein expression differences of ATP2A3, PLA2G4A, and ITPK1. Results: In vitro, CnE inhibited TNBC cell proliferation in a concentration-dependent manner, with IC50 values of 420 ± 35 μg/mL (MDA-MB-231) and 380 ± 28 μg/mL (MDA-MB-468), showing maximal 68.5% inhibition at 800 μg/mL (p < 0.001). The TNBC xenograft model was successfully established, and tumours in the extract-treated group were markedly smaller than those in the saline group. On day 28, the tumour inhibition rate was 28.66%, significantly higher than that in the saline group (P < 0.05). Haematoxylin-eosin staining staining and TUNEL assay showed increased tumor necrosis and apoptosis induction.(P < 0.001). Proteomic analysis showed that among the 4,908 identified proteins, 80 were upregulated, and 7 were downregulated. Bioinformatics analysis indicated involvement in the extracellular matrix, fatty acid metabolism, cell apoptosis, ferroptosis, immune response, choline metabolism, and amino acid metabolism. Immunohistochemistry revealed increased expression of ATP2A3 (1.3-fold, p < 0.05), PLA2G4A (1.6-fold, p < 0.05) and ITPK1 (3.2-fold, p < 0.01) proteins in the extract group compared to the control group. Conclusion: CnE inhibits TNBC cell proliferation, suppresses tumor growth, The mechanism likely involves multiple biological processes and pathways, Key pathways included apoptosis, ferroptosis, and necroptosis signaling.
