HMGA1 as a prognostic biomarker for gliomas: expression patterns, survival correlations, and clinical insights from a Pakistani cohort.
Article in Journal of neuro-oncology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeHigh-Mobility Group A1 (HMGA1) is a chromatin-associated protein involved in regulating key cellular processes, including DNA transcription, replication, recombination, and repair. It is highly expressed during embryogenesis and reactivated in various cancers, where it contributes to tumor progression and metastasis. We investigated the prognostic significance of HMGA1 gene expression in gliomas by comparing its expression in normal brain tissue and different glioma grades.
methodsReal-time quantitative PCR (qPCR) was performed on 75 glioma samples obtained from Aga Khan University Hospital (Pakistan), along with 10 Normal Adjacent Tissue (NAT) samples. The correlation between HMGA1 expression and prognosis was evaluated using Kaplan-Meier (KM) plotter in glioma patients. Statistical analyses were conducted using the R platform and further validated through the online database Chinese Glioma Genome Atlas (CGGA) using online tools.
resultsHMGA1 expression was significantly upregulated in gliomas compared to NAT (p < 0.001) and increased with tumor grade (p = 0.015). High HMGA1 expression correlated with Ki-67 levels and was associated with worse survival (p = 0.0014). Patients with elevated HMGA1 had a 3.5-fold higher mortality risk (95% CI: 1.5-7.9, p = 0.003). ROC analysis yielded an AUC of 0.752, indicating its potential prognostic value.
conclusionHMGA1 overexpression is associated with poor prognosis in gliomas, suggesting its potential as a prognostic marker. However, further validation is needed to confirm its clinical utility.
