Unplanned 6-month readmissions and in-hospital outcomes for the management of acute intermediate- and high-risk pulmonary embolism: comparisons of endovascular interventions.
Article in CVIR endovascular, 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
backgroundTo compare catheter directed thrombolysis (CDT) and endovascular mechanical thrombectomy (MT) for acute intermediate-risk and high-risk pulmonary embolism (PE) with respect to unplanned 6-month readmissions and in-hospital outcomes using a national database.
methodsThe NRD was queried from 2016 to 2022 for adult patients with acute nonseptic PE who received either CDT or MT. Inverse probability weighted regression adjustment was used to compare CDT and MT with regard to in-hospital mortality, unplanned 6-month readmissions, discharge other than home (DOTH), total cost as well as gastrointestinal bleeding (GIB), intracranial hemorrhage (ICH), blood transfusion at index admission, and 6-month readmission. Results are depicted as average treatment effect (ATE).
resultsA total of 28,376 patients were identified; 18,168 (64%) underwent CDT and 10,208 (36%) underwent MT. There was a total of 3,945 patients with high risk PE (13.9%). Compared to CDT, the ATE of MT was higher with regards to in-hospital mortality (ATE: 0.007; p = 0.048), DOTH (ATE: 0.031; p < 0.001), ICH (ATE: 0.006; p < 0.001), total cost at index admission (ATE: 0.118; p < 0.001), GIB at 6 months (ATE: 0.004; p = 0.023), blood transfusions at 6 months (ATE: 0.006; p = 0.017) as well as death at final follow-up (ATE: 0.009; p = 0.025). The ATE was similar between CDT and MT with regard to GIB (p = 0.097) at index admission as well as unplanned 6-month readmission (p = 0.10), ICH (p = 0.11), and recurrent PE (p = 0.39) at 6 months.
conclusionMT was associated with higher rates of mortality, DOTH, ICH, and total cost at index admission as well as GIB, blood transfusions, and mortality at 6 months. MT was associated with similar rates of GIB at index admission, as well as unplanned readmission, ICH, and recurrent PE at 6 months.
