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: This study aimed to investigate the association between serum triglyceride (TG) levels and the presence of hypertension in patients with coronary artery disease (CAD) and hypertension undergoing percutaneous coronary intervention (PCI). Methods: This retrospective study included 3,150 patients diagnossed with CAD who underwent PCI after coronary angiography (CAG) at the Department of Cardiology, The Second Affiliated Hospital of Harbin Medical University, between September 8, 2019, and February 27, 2022. Serum TG levels were measured within 24 h of admission, and covariates, including demographic data, clinical characteristics, and serum biomarkers, were collected. Multivariate logistic regression models were used to analyze the association between TG levels and hypertension. Results: A total of 36.8% (1,159/3,150) were ultimately included in the analysis, with 27.5% (319/1,159) presenting acute myocardial infarction (AMI). After adjusting for multiple confounding factors, TG levels were found to be independently associated with the presence of hypertension [odds ratio [OR] = 1.23, 95% confidence interval [CI]: 1.03-1.47]. When grouped by TG level quartiles, compared with the Q1 group, Q2, Q3, and Q4 showed significantly higher risks of hypertension in patients with CAD [OR, 95% CI: 1.98 (1.39-2.81), 1.80 (1.25-2.58), and 2.61 (1.68-4.05), respectively]. Furthermore, an additional analysis revealed a nonlinear relationship between TG and hypertension, characterized by a pronounced saturation effect which was particularly pronounced in patients with ejection fraction <50%. Conclusion: This study is the first to demonstrate a J-shaped association between TG level and hypertension presence in patients with CAD after PCI, with an inflection point of 3.86 mmol/L. This association was more pronounced in patients with reduced EF, suggesting that in patients with cardiac dysfunction, there is a stronger association between TG levels and hypertension, which may warrant further investigation into the clinical benefits of TG management in this subgroup.3.
