Multidisciplinary team for antithrombotics management and clinical outcomes in older adults with atrial fibrillation: a target trial emulation.
Observational study in BMC medicine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04932603 (Impact of Multidisciplinary Team Approach on the Utilization and Risks Related to Antithrombotic Drugs in Older Patients With Atrial Fibrillation), which is not on this 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.

Abstract
backgroundRecent international guidelines emphasize a multidisciplinary, patient-centered approach to managing atrial fibrillation (AF), particularly regarding antithrombotic (antiplatelet and anticoagulant) management. These guidelines advocate establishing multidisciplinary AF teams, but the clinical benefits of this approach for high-risk, clinically complex subgroups-particularly among very old and frail patients-remain uncertain. Our objective was to evaluate the impact of a hospital multidisciplinary team meeting dedicated to antithrombotics management on a composite measure of all-cause death, major thromboembolic events, or major or clinically relevant bleeding within 6 months in older adults with AF.
methodsA prospective multicenter cohort study was conducted in five acute geriatric departments in the Paris area between May 2021 and January 2024. Using a target trial emulation approach (cloning, censoring, weighting strategies), outcomes were analyzed in patients aged ≥ 75 years with AF or atrial flutter, followed in the geriatric departments (via outpatient consultation or hospitalization; > 98% were hospitalized). Participants were followed for 6 months or until death. The primary exposure was a hospital multidisciplinary team meeting within 45 days of inclusion, involving geriatricians, cardiologists, neurovascular specialists, and hemostasis experts. Cumulative incidences were estimated using the reverse Kaplan-Meier method.
resultsThe study included 818 patients, 138 (16.9%) in the hospital multidisciplinary-team meeting arm (median age 89 (Q1Q3 84-93), 57% female). The 6-month cumulative incidence of the primary composite outcome was 35.3% (95% CI, 29.6 to 41.8) in the multidisciplinary-team meeting arm and 36.2% (95% CI, 32.2 to 40.1) in the control arm (risk difference - 0.9 (95% CI, - 7.5 to 6.0); p = .79). The 2 arms did not differ in individual events within the composite measure.
conclusionsA hospital multidisciplinary team meeting dedicated to antithrombotics management in older adults with AF was not associated with a reduction in all-cause death, major thromboembolic events, or major or clinically relevant bleeding within 6 months. These findings should be interpreted with caution due to the observational design and potential for residual confounding.
