Antithrombotic Therapy After Percutaneous Left Atrial Appendage Closure: Results From the TERMINATOR Registry.
Article in JACC. Asia, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundAlthough warfarin plus aspirin as an antithrombotic regimen after percutaneous left atrial appendage closure (LAAC) has been proposed in initial randomized trials, other regimens are often used in real-world settings because of differences in patient characteristics and the widespread use of direct oral anticoagulant agents (DOACs). However, variations in antithrombotic regimens after LAAC and their impact on major adverse events remain unclear in Asian patients, who have a higher risk for bleeding and a lower risk for ischemic events than non-Asian patients.
objectivesThe aim of this study was to investigate variations in antithrombotic regimens after LAAC and the impact of these regimens on major adverse events.
methodsA total of 1,449 patients who underwent LAAC between August 2019 and May 2023 were analyzed in a multicenter, observational, real-world registry from Japan. The outcomes were the antithrombotic regimens at discharge and major adverse events at 6 months according to these regimens. Covariate adjustment using propensity scores was performed to compare the impact of antithrombotic regimens on major adverse events.
resultsMedian follow-up duration was 184 days (Q1-Q3: 174-195 days). The 5 most common antithrombotic regimens at discharge were DOAC only (32.4% [469 of 1,449]), DOAC and aspirin (30.3% [439 of 1,449]), warfarin and aspirin (13.7% [199 of 1,449]), DOAC and P2Y
conclusionsIn a real-world registry from Japan, the initial antithrombotic regimen after LAAC was not commonly used, and differences in antithrombotic regimens did not significantly affect short-term clinical outcomes.
