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
backgroundSpinal cord injury (SCI) inflicts a severe burden on patients and lacks effective treatments. Owing to the poor regenerative capabilities of endogenous oligodendrocyte precursor cells (OPCs) following SCI, there is a growing interest in alternative sources, such as human umbilical cord mesenchymal stem cells (HUCMSCs). TET3 is a key DNA demethylase that plays an important role in neural differentiation, but its role in OPC formation is not well understood. This study aimed to explore the TET3-mediated one-step induction of HUCMSCs into OPCs.
methodsIn vitro, HUCMSCs were induced into OPCs following TET3 overexpression. Changes of methylation and hydroxymethylation during differentiation were monitored, mechanisms involved in the TET3-driven HUCMSC differentiation into OPCs were identified by RNA sequencing. Methylation levels in NG2 and PDGFRA promoter region were detected using Bisulfite Polymerase Chain Reaction (BSP).In vivo, therapeutic effects of iOPCs were evaluated through a rat Allen's SCI model.
resultsThe in vitro analysis confirmed that TET3 enhances HUCMSC differentiation into OPCs, validitied by specific marker expression. The induced OPCs (iOPCs) exhibited methylation and hydroxymethylation patterns similar to native OPCs. BSP analysis demonstrated that TET3 overexpression significantly reduced CpG island methylation in the NG2 and PDGFRA promoter regions. RNA sequencing revealed that TET3 induces iOPCs to express a series of genes essential for OPC formation while inhibiting the signaling pathways that hinder OPC development. In a rat model of SCI, TET3-overexpressing HUCMSCs appear to have the potential to differentiate into iOPCs in vivo, suppressed secondary injury, and promoted functional recovery. The therapeutic effects of iOPCs on SCI were superior to those of standard mesenchymal stem cell treatments.
conclusionsOur study demonstrated that TET3-mediated demethylation reshapes the methylation patterns of HUCMSCs, enabling their efficient one-step conversion into OPCs and significantly reducing the time required for cell preparation. This approach offers a potential strategy for early intervention in SCI. In an SCI model, TET3-induced OPCs contributed to spinal cord repair, providing novel insights into cell therapy strategies for SCI through the lens of methylation regulation.
