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
Objectives: The purpose of this study is to explore the clinical value and molecular role of the peroxiredoxins (PRDXs) family in prostate cancer (PCa). Methods: We first analyzed the differentially expressed genes (DEGs) in Prostatic Adenocarcinoma (PRAD) using the Cancer Genome Atlas (TCGA) database, and then demonstrated the expression of six members of the PRDXs family in PRAD. Subsequently, we evaluated the expression of the PRDXs family using PCa cells and tissues. we also analyzed the diagnosis and overall survival (OS) of the PRDXs family in PCa. We used online tools to analyze the expression of PRDX4 in pan-cancer, the proteins interacting with it, as well as the amino acid regions and sites to pathogenicity. We used CCK8 and transwell assay to detect the proliferation and invasion of PCa cells after silencing PRDX4. Finally, we predicted traditional Chinese medicine drugs targeting PCa with PRDX4. Results: We found that PRDX2 and PRDX4 were highly expressed in PRAD through the TCGA database. Compared with prostate epithelial cells, PRDX2, PRDX3, PRDX4, and PRDX6 were expressed higher in PCa cells. In PCa tissues, the PRDXs family is widely expressed positively (P<0.05). The PRDXs family has relatively low diagnostic value in PCa, except for PRDX4. Based on the above results, we selected PRDX4 for molecular role detection. We found that the expression of PRDX4 in PCa was higher than that in more than half of the cancer types in pan-cancer. We found that there are eight proteins interacting with PRDX4. The pathogenic amino acid regions and sites of PRDX4 protein mutation that are prone to disease were mainly concentrated in the area after the 50th amino acid. We found that silencing PRDX4 slowed down the proliferation and invasion of PCa cells. Finally, we found that there are 14 traditional Chinese medicines targeting PCa with PRDX4, among which 5 have statistical differences, and Shi Liu Zi may be the best targeted traditional Chinese medicine drug. Conclusion: This study found that PRDX4 is highly expressed in PCa, which may promote the phenotypic progression of PCa cells and has high clinical value.
