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
backgroundThis study aims to identify genes with a high likelihood of genetic variation, significant expression differences, and prognostic implications in colorectal cancer (CRC) patients. The research also seeks to investigate the role and mechanisms of key genes in CRC through the analysis of health information data and a combination of internal and external experiments.
methodsThe sequence information of CRC patients was obtained from the Cancer Genome Atlas Program (TCGA) database. Key genes were identified through differential expression analysis, enrichment analysis, interaction analysis, and survival curve analysis. Subsequently, Growth and Differentiation Factor 10 (GDF10) overexpression and knockout cell models were developed to investigate the impact of GDF10 on CRC cells using assays such as CCK8, flow cytometry, Transwell, and subcutaneous tumor formation in nude mice. Mechanistically, the effects of GDF10 and IGF2 genes on autophagy, apoptosis, and ferroptosis were studied by introducing different death pathway inhibitors. Changes in reactive oxygen species (ROS), GSH, and MDA levels in cells following silencing were also assessed. Furthermore, the influence of GDF10 and its interacting protein IGF2 on ferroptosis was evaluated through ELISA and fluorescence staining.
resultsThe analysis of patients in the TCGA database revealed that GDF10 expression was low in microsatellite stable (MSS) type and high in microsatellite instability (MSI) type. It was found to interact with IGF2, with low expression associated with a better prognosis. Overexpression of GDF10 was shown to significantly enhance the proliferation and invasion abilities of CRC cells, whereas low expression promoted cell apoptosis. Within the pathways of autophagy, apoptosis, and ferroptosis, low expression of GDF10 primarily regulated ferroptosis in cells. This regulation involved promoting the iron-dependent lipid oxidation process by mediating binding with IGF2, leading to increased concentrations of iron ions and oxidative metabolites in cells. This process also reduced the formation of lipid droplets and inhibited tumor development.
conclusionGDF10 plays a crucial role in regulating ferroptosis in CRC cells through mediating IGF2 interaction, suggesting it as a promising therapeutic target for CRC.
