Association of TRDMT1 Gene Polymorphisms With Neuroblastoma Susceptibility: Insights From a Case-Control Study.

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
Neuroblastoma is the most common extracranial solid tumour in children, and genetic susceptibility plays a crucial role in its development. The impact of tRNA Dimethyltransferase 1 (TRDMT1), a primary methyltransferase catalysing 5-methylcytosine (m5C) RNA modification, on neuroblastoma susceptibility remains unexplored. We conducted a case-control study involving 402 neuroblastoma patients and 473 controls from Jiangsu, China. TRDMT1 polymorphisms (rs7074891 T>C, rs10904887 T>C and rs2273734 C>T) were genotyped via the TaqMan assay. Logistic regression was used to assess odds ratios (ORs) and 95% confidence intervals (CIs), while stratification analysis and expression quantitative trait locus (eQTL) analysis were used to examine subgroup-specific effects and regulatory impacts. Additionally, clinical correlation analysis and survival analysis were performed on neuroblastoma datasets used to evaluate. The rs7074891 TC/CC genotype reduced neuroblastoma risk (adjusted OR = 0.75, 95% CI = 0.57-0.98, p = 0.036), especially in children aged ≤ 18 months and those with mediastinal-origin tumours. Conversely, the rs10904887 CC (adjusted OR = 1.73, 95% CI = 1.27-2.38, p = 0.0006) and rs2273734 TT genotypes (adjusted OR = 1.80, 95% CI = 1.09-2.97, p = 0.023) were associated with increased risk, with distinct subgroup-specific effects. Combined 1-3 risk genotypes further confirmed increased susceptibility (adjusted OR = 1.81, 95% CI = 1.38-2.37, p < 0.0001), particularly in males and older children. eQTL analysis revealed that the rs7074891 C and rs10904887 C alleles increased TRDMT1 expression, whereas the rs2273734 T allele decreased it. Elevated TRDMT1 expression was correlated with poor prognosis and high-risk clinical features. TRDMT1 polymorphisms are significantly associated with neuroblastoma susceptibility, providing insights into their genetic and epigenetic mechanisms and potential as biomarkers and therapeutic targets.
