Association between ALDH2 rs671 polymorphism and susceptibility to non-valvular atrial fibrillation in a Chinese population: a large-scale 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
Non-valvular atrial fibrillation (NVAF) is the most common arrhythmia worldwide, with a steadily rising incidence and prevalence, posing a significant public health burden. Oxidative stress is recognized as a key driver of atrial remodeling and arrhythmogenesis. Mitochondrial aldehyde dehydrogenase 2 (ALDH2) plays a critical role in detoxifying reactive aldehydes, and the rs671 single-nucleotide polymorphism (G→A, Glu504Lys) markedly reduces enzymatic activity, with a high prevalence in East Asian populations. In this retrospective study, we analyzed 403 NVAF patients and 14,326 hospitalized controls from Meizhou People's Hospital (2016-2020), aged ≥30 years (1:35.5 ratio), and constructed multiple propensity score-matched cohorts (1:15 to 1:2) to examine the association between ALDH2 rs671 and NVAF. The A allele frequency was significantly higher in NVAF patients than in the controls (32.0% vs. 24.2%, P < 0.001), causing an increased NVAF risk (OR = 1.472, 95% CI: 1.266-1.711). Multivariate logistic regression identified the GA genotype (OR = 1.681, 95% CI: 1.360-2.078, P < 0.001) and the AA genotype (OR = 1.558, 95% CI: 1.058-2.296, P = 0.025) as independent risk factors. Sensitivity analyses across various matching ratios confirmed the robustness of the association. Other independent risk factors included male sex, advanced age, hypertension, diabetes, coronary heart disease, and COPD.
