Contemporary reperfusion therapies in patients with intermediate- and high-risk pulmonary embolism.
Article in Thrombosis research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundWithout clear guidelines, contemporary use of reperfusion therapy for intermediate-risk and high-risk pulmonary embolism (PE) may vary widely. We assessed variation and trends in use of reperfusion therapies (systemic thrombolysis, catheter-directed thrombolysis, mechanical thrombectomy) and how practices change when hospitals adopt mechanical thrombectomy.
methodsUsing the national Premier Inc. AI Database (2016-2022), we identified adults with intermediate-risk or high-risk PE. For each reperfusion therapy, our primary outcome was intraclass correlation coefficient (ICC, representing between-hospital variation unexplained by patient/hospital characteristics; a priori, ICC > 15 % deemed "high" variation) and proportion trends over time with hierarchical regression models and assessed trends in use. Among hospitals that adopted mechanical thrombectomy, we conducted interrupted time series analysis to assess changes in use of systemic thrombolysis, catheter-directed thrombolysis, and any reperfusion therapy.
resultsWe assessed 13,777 patients (11,846 intermediate-risk; 1931 high-risk PE) admitted in the US between 2016 and 2022. High variation was observed in catheter-directed thrombolysis (intermediate-risk: ICC 23.1 %; high-risk: ICC 23.8 %) and thrombectomy use (intermediate-risk: ICC 35.4 %; high-risk: ICC 25.1 %). Mechanical thrombectomy use increased from 0.6 % to 14.3 % between 2016 and 2022 (p < 0.001). Hospital adoption of mechanical thrombectomy was associated with a deceleration in growth of catheter-directed thrombolysis rates.
conclusionsAmong patients with intermediate-risk and high-risk PE in the US, reperfusion therapy use varies widely, and the use of mechanical thrombectomy increased between 2016 and 2022. At hospitals adopting mechanical thrombectomy, thrombectomy supplants catheter-directed thrombolysis without increasing total use of reperfusion therapy. These results raise questions about standardization of care, optimal resource allocation, and impact on patient outcomes.
