Investigation of Genetic Variations in APLN and APLNR Genes and Their Potential Role in Cardiovascular Diseases.
Article in Reports of biochemistry & molecular biology, 2025. 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
Background: Apelin is a naturally produced ligand for G protein-linked receptors derived from a 77-amino acid pre-propeptide. The effect of apelin on the development of cardiovascular diseases and the relationship between the apelin gene and the apelin receptor. Methods: The case-control study included 100 participants of people suffering from cardiovascular diseases. Samples were collected from patients hospitalized at the Nasiriyah Heart Center between November 10, 2023, and February 15, 2024. The study also included 50 healthy people who did not suffer from cardiovascular disease. The lipid profile was measured by spectrophotometer, and the Apelin level was measured by enzyme-linked immunosorbent assay. Four single nucleotide polymorphisms for Apelin (APLN) and Apelin receptor (APLNR) were chosen, and Sanger sequencing was used to genotype them accurately. Results: The findings indicated that there was no statistically significant difference in age between the two groups. Upon comparing the age demographics of the two groups in the study, the results indicated a lack of statistical significance in the levels of APLN or the lipid profile, despite the case group exhibiting markedly elevated Apelin and lipid levels compared to the control group. After multiple test adjustments (P < 0.05), neither the APLN rs2235310T allele nor the APLNR rs9943582 allele demonstrated an association with an elevated risk of coronary heart disease. Conclusions: The investigation revealed no significant age variations or genetic correlations associated with CHD risk. However, rather than age or genetic differences, elevated apelin and cholesterol levels in the case group indicate these factors as primary contributors to cardiovascular risk.
