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: Recently, central precocious puberty (CPP) is becoming a major public health concern worldwide due to its enhanced prevalence. Traditional Chinese medicine (TCM) compounds offer unique therapeutic advantages for treating this condition, and luteolin, a bioactive monomer compound commonly found in these herbs, has drawn increasing attention. However, the therapeutic effects of luteolin on CPP development remain unclear. Methods: A danazol-induced CPP model was established in Sprague-Dawley rats to explore the potential therapeutic effects of luteolin. Sexual development indicators, organ coefficients, gonadal histopathology, and sex hormone levels were evaluated to assess treatment outcomes. Additionally, a comprehensive approach involving network pharmacology, molecular docking, and transcriptomic analyses was used to identify luteolin-related signaling pathways and target proteins involved in CPP treatment. Finally, we carried out enzyme-linked immunosorbent assay (ELISA) and reverse transcription- quantitative polymerase chain reaction (RT-qPCR) for finding validation and exploring the underlying mechanisms. Results: In the danazol-induced CPP model, luteolin treatment significantly decreased the abundances of Estradiol (E2), luteinizing hormone serum, and follicle-stimulating hormone in sera; reduced organ coefficients and ovarian and uterine wet weights; and delayed vaginal opening. Network pharmacology and transcriptomic analyses revealed that luteolin exerted its therapeutic effects mainly by modulating immune and inflammatory pathways, including the tumor necrosis factor-α, Toll-like receptor, and IL-17 signaling pathways. Molecular docking demonstrated stable binding of luteolin to key targets such as Cxcl10, Cxcl11, Stat1, Tlr3, and Irf7. ELISA results confirmed that luteolin inhibited pro-inflammatory cytokines while promoting anti-inflammatory factors in the CPP model. Furthermore, RT-qPCR analysis revealed that luteolin enhanced Irf7 and Stat1 expression within the Toll-like receptor pathway, mainly by upregulating Tlr3, thereby enhancing the abundances of downstream effector molecules Cxcl10 and Cxcl11. Conclusion: This study is the first to determine that luteolin ameliorates CPP via the Toll-like receptor signaling pathway. These findings enhance our understanding of luteolin's pharmacological actions and support its potential role in CPP treatment.
