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
Gastrointestinal angiodysplasia (GIAD) is the most prevalent vascular malformation of the gastrointestinal (GI) tract, primarily affecting elderly individuals, with the colon being the most common site of involvement. Patients with GIAD often present with cardiovascular comorbidities such as hypertension, increased aortic stiffness, and left ventricular hypertrophy (LVH). This study aimed to evaluate the prevalence of hypertension and its association with aortic stiffness in patients diagnosed with GIAD with particular attention to the role of non-dipper blood pressure patterns. Additionally, the predictive value of inflammatory biomarkers-including the C-reactive protein to albumin ratio (CAR), blood urea nitrogen to albumin ratio (BAR), neutrophil-to-lymphocyte ratio (NLR), lymphocyte-to-C-reactive protein ratio (LCR), and systemic immune response index (SIRI) was investigated concerning vascular risk and disease pathophysiology. A total of 25 patients with GIAD and 25 matched controls were included. All participants underwent comprehensive cardiovascular evaluation, including physical examination, electrocardiography, transthoracic echocardiography, and 24 h ambulatory blood pressure monitoring (ABPM). Demographic characteristics, biochemical parameters, echocardiographic indices, and ABPM findings were analyzed. Receiver operating characteristic (ROC) curve analysis, area under curve (AUC) and multivariate regression models were used to assess the predictive value of inflammatory biomarkers. GIADs were predominantly localized in the colon (40%). Compared to controls, patients exhibited significantly increased aortic stiffness, greater aortic systolic and diastolic diameters, and a higher prevalence of LVH. The non-dipper blood pressure pattern was notably more frequent among patients (84% vs. 4%,
