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/
objectivesMetastatic prostate cancer (PCa) is the leading cause of cancer-related deaths and a major contributor to cancer mortality in men. Most patients with metastatic PCa eventually develop metastatic castration-resistant prostate cancer (mCRPC), characterized by resistance to treatment with androgen-deprivation therapy, and often later the development of resistance to other types of agents. MAGMAS, a 13.8 kDa mitochondrial-associated protein, facilitates the import of nuclear-encoded proteins into the mitochondrial matrix. Overexpression of MAGMAS has been observed in several aggressive cancers, including breast, glioblastoma, and prostate cancer. When overexpressed, MAGMAS acts as a cytoprotective protein by scavenging reactive oxygen species (ROS), maintaining ROS levels that support cell proliferation while avoiding the induction of apoptosis. This study investigates the role of MAGMAS in therapy resistance in PCa cells. METHODS/
resultsQuantitative immunoblotting revealed that MAGMAS is endogenously upregulated in docetaxel-resistant (DR) PCa cell lines compared to their docetaxel-sensitive parental counterparts. While MAGMAS depletion alone did not affect the survival of DR cells, it significantly sensitized them to docetaxel (DTX), as indicated by a marked reduction in clonogenic potential. Additionally, transient knockdown of MAGMAS in these resistant cells significantly decreased the levels of ABCB1 protein. Consistent with these findings, sub-therapeutic inhibition of MAGMAS using the novel BT#9 inhibitor, in combination with increasing concentrations of DTX, enhanced the sensitivity of DR cells to DTX, as demonstrated by proliferation and clonogenic assays. Lastly, RNA tumor expression predicts overall survival (OS).
conclusionsThese results implicate MAGMAS in PCa chemoresistance and suggest that targeting this protein could provide a novel therapeutic strategy for treating DR tumors.
