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
Cancer stem cells are pivotal in cancer progression, yet the mechanisms underlying the stemness properties of neuroblastoma cells remain largely unclear. By analyzing data from the TARGET-NBL and GEO databases, WDR72 is identified as a cancer stem cell marker that significantly correlates with high-risk of neuroblastoma and poor prognosis in neuroblastoma patients. It is found that knocking down WDR72 in neuroblastoma cells suppresses cell proliferation and migration, while inducing apoptosis. An increased expression of WDR72 is detected in neuroblastoma cells with enhanced stemness properties, while silencing WDR72 reduces the stemness of these cells. Mechanistically, we find that the upregulation of WDR72 is mediated by m6A modifications in its 3' UTR induced by the METTL14-IGF2BP1 axis. Further investigation into the downstream regulatory mechanisms of WDR72 demonstrates that WDR72 interacts with TRIM31, blocking the ubiquitination and subsequent degradation of the CBX8 protein. This interaction stabilizes CBX8, contributing to the maintenance of neuroblastoma cell stemness. This study reveals that the upregulation of WDR72 via the METTL14-IGF2BP1 axis enhances the stemness properties of neuroblastoma cells by stabilizing CBX8 through interaction with TRIM31. These findings provide new insights into the molecular mechanisms driving neuroblastoma malignancy and offer potential therapeutic targets for patients with neuroblastoma.
