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
Prostate cancer ranks second among the most common malignant neoplasms in men worldwide. Fruit extracts with potential anti-prostate cancer properties have gained increasing attention, with the most notable belonging to the Annonaceae family, including Araticum (Annona crassiflora Mart). In this study, we aimed to evaluate the chemopreventive and anti-inflammatory potential of Araticum seed extract (Annona crassiflora Mart) on the ventral prostate lobe of Transgenic Adenocarcinoma of the Mouse Prostate (TRAMP) model. Sixty male TRAMP mice, aged 8 and 12 weeks, were divided into four groups: two groups received the extract at a dose of 100 mg/kg body weight, and two control groups received equivalent volumes of water and DMSO (Dimethyl Sulfoxide). After 30 days, animals were euthanized and ventral prostate samples were collected for morphological evaluation by light microscopy, immunohistochemistry, and Western blotting. Treatment with Araticum seed extract delayed the progression of premalignant and malignant lesions (HGPIN and adenocarcinoma) and preserved healthy tissue. The extract showed antiproliferative activity, reducing PCNA, IGFR-1, and AR protein levels. Inflammatory signaling was suppressed via Toll-like receptor pathways, with decreased NFκB, TNF-α, and other inflammatory markers. Moreover, the extract reduced BCL-2 expression and promoted caspase activation, suggesting pro-apoptotic protection. In conclusion, treatment with Araticum seed extract demonstrated promising chemopreventive activity, effectively reducing the progression of epithelial lesions in the ventral prostate lobe of TRAMP mice and may be suggested as a potential chemopreventive agent in combined prostate cancer therapies.
