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
backgroundComputed tomography (CT) is a first line imaging tool for staging of esophageal cancer (EC). Previous studies have shown promising results of the prognostic relevance of vessel calcifications quantified by CT, especially coronary and aortic calcifications, in oncological patients. The aim of this study was to analyze the prognostic relevance of aortic calcification assessed in staging CT in patients with EC undergoing curative treatment.
methodsAll patients with EC treated with neoadjuvant therapy followed by curative resection at the University of Leipzig Medical Center, a tertiary care hospital, were retrospectively evaluated between 2016 and 2023. A total of 89 patients were included in the analysis. Abdominal aorta and iliac artery calcification volume was measured in a semi-automated fashion at baseline before neoadjuvant therapy using staging CT images. The primary endpoint was overall survival and disease-free survival was assessed as a secondary endpoint. For statistical analysis group differences were calculated using the Mann-Whitney-U test. Kaplan-Meier curves and multivariable Cox regression analysis were used to test the effect of aortic calcification volume and clinical variables on mortality.
resultsIn univariable Cox regression, higher abdominal aortic calcification volume was significantly associated with shorter overall survival (Hazard ratio (HR) 1.259 per 1 cm³, 95% CI: 1.100-1.411, p < 0.001) and disease-free survival (HR 1.279 per 1 cm³, 95% CI: 1.135-1.411, p < 0.001). The abdominal aortic calcification volume remained an independent predictor of overall survival in multivariable analysis (HR 1.248, 95% CI 1.069-1.458, p = 0.005). Kaplan-Meier analyses demonstrated progressively reduced overall survival and disease-free survival with increasing abdominal aortic calcification volume.
conclusionsCT-quantified abdominal aortic calcification provides independent prognostic information for both overall and disease-free survival in patients with EC undergoing neoadjuvant therapy followed by curative resection. Prospective evaluations of CT-defined vessel calcification and potential translation in clinical routine seem promising.
