1 · What the graph read from it

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.

2 · The registry

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

Benign prostate hyperplasia (BPH) is an age-related disease in men characterized by the growth of prostate cells and hyperproliferation of prostate tissue. This condition is closely related to chronic inflammation. In this study, we highlight the therapeutic efficacy of ellagic acid (EA) for BPH by focusing on the AR signaling axis and STAT3. To investigate the effect of EA on BPH, we used EA, a phytochemical abundant in fruits and vegetables, to treat testosterone propionate (TP)-induced BPH rats and RWPE-1 human prostate epithelial cells. The EA treatment reduced prostate weight, prostate epithelial thickness, and serum DHT levels in the TP-induced BPH rat model. In addition, EA improved testicular injury by increasing antioxidant enzymes in testis of the BPH rats. EA reduced the protein levels of AR, 5AR2, and PSA. It also induced apoptosis by regulating Bax, Bcl_xL, cytochrome c, caspase 9, and caspase 3 with increasing mitochondrial dynamics. Furthermore, EA reduced the expression of IL-6, TNF-α, and NF-κB, as well as phosphorylation of STAT3 and IκBα. These findings were also confirmed in TP-treated RWPE-1 cells. Overall, our data provide evidence of the role of EA in improving BPH through inhibition of AR and the STAT3 pathway.
