Polymorphic variants and risk of diabetic peripheral neuropathy in patients with type 2 diabetes mellitus: systematic review and meta-analysis.

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
backgroundNeuropathy is a frequent complication of diabetes mellitus, a disease that is growing exponentially worldwide. Genetic research has emerged as an important tool for better understanding its predisposition, although a systematic synthesis of existing evidence is needed to better comprehend its association. The objective of this review was to determine the association between polymorphic variants identified through massive genomic testing and the risk of peripheral diabetic neuropathy in patients with type 2 diabetes mellitus.
methodsInclusion criteria were case-control, cohort, and cross-sectional studies examining polymorphic variants and diabetic neuropathy (DNP) risk in type 2 diabetes, studies using GWAS, EWAS, or microarray for identifying genetic polymorphisms, studies involving adults, and articles in English or Spanish. Exclusion criteria included case reports, case series, ecological studies, editor letters, reviews, or secondary studies and conference abstracts. Exhaustive search in PubMed, Scopus, and Web of Science databases, using keywords. Risk of bias was determined through Newcastle-Ottawa scale. A qualitative synthesis of the results was performed (frequency), including meta-analysis where applicable (forest plot and funnel plot).
resultsThe searching strategy identified 370 studies, from which 7 were chosen for the systematic review, included 9478 participants. The quality of the studies was mostly good, but a significant heterogeneity in methods was found. We identify a significant association between peripheral neuropathy and plenty of single nucleotide variants (SNVs). Just the SNV rs10555080 in the gene THEG5 showed a higher likelihood of neuropathy (OR:1,34; IC 95%: 1,19 - 1,49). DISCUSSION: This study faced limitations due to heterogeneity in DNP definitions, genotyping methods, and a focus on white and Arab populations, limiting generalization. Only English and Spanish articles were included, potentially excluding relevant research in other languages. Multiple SNVs were identified through genomic testing that were associated with peripheral diabetic neuropathy in patients with type 2 diabetes mellitus; however, the SNVs were not similar between studies.
