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
backgroundNeuroblastoma (NB) is a well-known pediatric malignancy intertwined with neurodevelopment. Previously implicated in neuronal differentiation, Zinc Finger Protein 536 (ZNF536) has emerged as a promising prognostic and immune-related biomarker in our pancancer analysis.
methodsSingle-cell RNA transcriptome sequencing, bulk transcriptome analysis, and immunohistochemistry were used to assess ZNF536 expression and its association with prognosis. Cell proliferation, migration, invasion, and differentiation in ZNF536-knockdown NB cell lines were detected to evaluate the effect of ZNF536 on tumor cells. Vascular Endothelial Growth Factor Receptor 2 (VEGFR2), a potential target of ZNF536, and its downstream PI3K/AKT signaling cascade were investigated using transcriptome sequencing, CUT&Tag, quantitative real-time PCR (qRT-PCR), and Western blotting. The role of ZNF536 in tumorigenesis and the potential regulation axis was evaluated in vivo using a BALB/c nude mouse xenograft tumor model.
resultsZNF536 mRNA and protein expression were significantly higher in NB patients with poor prognosis. In vitro, ZNF536 knockdown curtailed proliferation, migration, and invasion of NB cells while fostering differentiation. ZNF536 regulated VEGFR2 expression, thus activating the PI3K-AKT pathway. In vivo, ZNF536 knockdown reduced tumor growth and proliferation via the VEGFR2-PI3K-AKT pathway.
conclusionZNF536 resulted as a novel prognostic biomarker in NB, promoting oncogenesis through VEGFR2-PI3K-AKT signaling axis modulation, suggesting its therapeutic potential in managing NB progression.
