Evaluation of protein expression and oxidative stress index in Duchenne muscular dystrophy.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe severe, degenerative muscle condition known as Duchenne Muscular Dystrophy (DMD) typically manifests in early childhood.
objectiveThis study aims to investigate how DMD cases express the genes for Ewing's Tumor-associated Antigen 1 (ETAA1), Topoisomerase IIβ-binding protein 1 (TOPBP1), and ATR (Ataxia Telangiectasia and Rad3-related). SUBJECTS AND
methodsA total of 50 ambulatory male patients with DMD attending pediatric neurology clinic at Menoufia University Hospital were included and compared to 25 healthy control males matched for age. General clinical information, neurological information, and laboratory tests were performed. This included measuring serum levels of creatine phosphokinase CPK, human creatine kinase, muscle (CK-mm), human lactate dehydrogenase (LDH), total antioxidant status (TAS), total oxidant status (TOS), and quantitative expression of the genes ETAA1, TOPBP1, and ATR.
resultsIn contrast to those in good health, the expression levels of the ETAA1, TOPBP1, and ATR genes were significantly greater in DMD cases. Additionally blood levels of CPK, CK-mm, LDH, and TOS were significantly higher in DMD than those of healthy individuals.
conclusionThe gene expression of ETAA1, TOPBP1, and ATR is substantially elevated in cases with severe DMD, making them potentially significant indicators of the severity of DMD cases. IMPACT: This study evaluates the expression of DNA damage response genes-ETAA1, TOPBP1, and ATR-in patients with Duchenne Muscular Dystrophy (DMD). The results demonstrate that DMD patients have much greater gene expression levels and oxidative stress indicators than healthy controls. These genes show a favorable correlation with clinical severity indicators such as CKMM, CPK, and LDH. Combining the three markers improves diagnostic sensitivity and specificity, indicating their potential as a multi-gene biomarker panel. The findings shed fresh light on DMD etiology by correlating genomic instability to disease progression and identifying possible molecular targets for early detection and future treatment approaches.
