Impact of concomitant deep vein thrombosis on outcomes of acute pulmonary embolism: Insights from the PERT consortium registry.
Article in Journal of vascular surgery. Venous and lymphatic disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveStudies have reported conflicting data regarding the prognostic significance of concomitant deep vein thrombosis (DVT) in acute pulmonary embolism (PE). Understanding the potential differences between PE with and without DVT is crucial for optimizing strategies.
methodsUsing data from The Pulmonary Embolism Response Teams Consortium Registry, this study examined the association between concomitant DVT and clinical outcomes in patients with predominantly acute intermediate- and high-risk PE. A secondary aim was to assess the impact of DVT on treatment selection, particularly the use of advanced therapies.
resultsAmong 7346 patients with acute PE, 5076 (69%) had concomitant DVT. Patients with DVT were more frequently classified as intermediate-risk compared with patients without DVT, including intermediate-high (59.31% vs 51.9%; P < .001) and intermediate-low risk PE (19.4% vs 17.7%; P < .001). The presence of DVT was significantly associated with higher odds of receiving advanced therapies (odds ratio [OR], 2.49; 95% confidence interval [CI], 2.14-2.81), particularly catheter-directed therapy (OR, 2.44; 95% CI, 2.12-2.83), with the strongest association observed in the intermediate- to high-risk group (OR, 2.67; 95% CI, 2.25-3.18). Concomitant proximal DVT was not associated with increased in-hospital mortality (OR, 0.87; 95% CI, 0.69-1.09), 30-day mortality (OR, 0.96; 95% CI, 0.77-1.20), 1-year mortality (OR, 0.87; 95% CI, 0.73-1.03), or intensive care unit admission (OR, 1.05; 95% CI, 0.93-1.20), after adjustment for advanced therapy use.
conclusionsIn this large contemporary cohort of predominantly intermediate- and high-risk PE, concomitant DVT was common and associated with more severe presentation and greater use of advanced therapies, but not with higher short- or long-term mortality.
