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
backgroundThe role of atherosclerosis in pulmonary embolism (PE) prognosis remains uncertain. Our study assesses characteristics and outcomes of acute PE patients according to the presence and extent of atherosclerotic disease.
methodsUsing data from the RIETE registry, acute PE patients were classified into three groups based on personal history: (1) polyvascular atherosclerosis, (2) single vascular atherosclerosis, and (3) no symptomatic atherosclerosis. Primary outcomes included recurrent PE and venous thromboembolism (VTE), arterial events, major bleeding, and all-cause death. Hazard ratios (HR) and Kaplan-Meier curves for clinical outcomes were estimated using Cox regression models.
resultsAmong 47,578 acute PE patients, 1,040 had polyvascular, 6,191 single-vascular, and 40,347 no atherosclerosis. During a median follow-up of 331 days, Adverse outcomes were more frequent in patients with atherosclerosis (vs. no atherosclerosis), rising with the number of affected vascular territories. Recurrent PE rates were 2.8, 1.6, and 1.2 per 100 patient-years in the polyvascular, single-vascular, and no atherosclerosis groups. Multivariable analysis showed a dose-dependent relationship between atherosclerosis and recurrent PE risk, with HRs of 3.2 (95% CI 1.7-5.9) and 1.6 (95% CI 1.1-2.3) for polyvascular and single-vascular disease (vs. no atherosclerosis). The risk of all-cause death followed a similar trend, with HRs of 1.3 (95% CI 1.1-1.6) and 1.2 (95% CI 1.1-1.4), respectively. Major bleeding appeared to be influenced by overall health status and antithrombotic therapy intensity.
conclusionAtherosclerosis in acute PE patients may serve as a marker of disease severity and lead independently to adverse outcomes, highlighting the importance of cardiovascular risk stratification.
