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
The cell cycle mechanism is an integration point where information is sent through an upstream signaling network, making it a potential target for cancer diagnosis and treatment. The LAP1 protein, encoded by the Tor1aip1 gene, is required to maintain the shape of the nuclear envelope and the progression of the cell cycle. The aim of this study was to determine the role of Tor1aip1 gene in PRAD development and its mechanism. We analyzed the expression and survival data of TOR1 AIP1 in PRAD patients in the TCGA database and verified the low expression of TOR1 AIP1 in prostate cancer by qPCR, western blot and immunohistology, which was correlated with the tumor stage and survival prognosis of PRAD. In addition, lentiviral vectors were used to mediate the up-regulation or down-regulation of TOR1 AIP1 expression in prostate cancer cells, and the effects of TOR1 AIP1 on tumor proliferation and related signaling pathways were investigated by cell counting kit- 8, colony formation assay, transwell assay, western blot, and flow cytometry. As a result, we found that TOR1 AIP1 enhances protein stability of p53 by directly interacting with p53, consequently inhibited tumor proliferation and invasion by inducing the cell cycle to be arrested in the S phase. Therefore, TOR1 AIP1 represents a promising therapeutic target in PRAD due to its ability to stabilize p53 and enhance its tumor-suppressive functions. Future studies should focus on elucidating its mechanisms, developing targeted therapies, and exploring its clinical potential in combination with existing treatments. By advancing our understanding of TOR1 AIP1, we may unlock new strategies for improving outcomes in PRAD patients.
