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
Glioblastoma (GBM) is a highly aggressive intracranial malignancy originating from neuroepithelial glial progenitors. The prominent intra- and intertumoral heterogeneity of GBM is a major driver of therapeutic resistance and frequent tumor recurrence. Cholesterol is an essential structural component of mammalian cell membranes and plays crucial roles in membrane trafficking and transmembrane signal transduction. As a key intracellular cholesterol transporter, the Niemann-Pick type C2 (NPC2) protein remains poorly characterized regarding its biological functions and clinical implications in GBM. In this study, immunohistochemical staining of clinical GBM specimens revealed that elevated NPC2 expression was significantly correlated with unfavorable patient prognosis. Consistent with clinical observations, genetic knockdown of NPC2 markedly suppressed the proliferation and invasion abilities of LN18 cells. Mechanistically, NPC2 silencing downregulated GPX4 expression at both transcriptional and translational levels, suggesting a potential regulatory relationship between NPC2 and the ferroptosis pathway. Collectively, these findings indicate that NPC2 may facilitate GBM malignant progression partially through modulating GPX4-mediated ferroptosis, thereby representing a tentative prognostic biomarker and a potential therapeutic target for GBM that requires further validation.
