Efficacy and safety of percutaneous left atrial appendage closure to prevent thromboembolic events in atrial fibrillation patients with high stroke and bleeding risk.
Observational study in Clinical research in cardiology : official journal of the German Cardiac Society, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 papers, 3 of them syntheses that pooled it.
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
aimsThe randomized PROTECT AF trial demonstrated non-inferiority of left atrial appendage (LAA) closure to oral anticoagulation with warfarin. Current guidelines give a class IIb recommendation for LAA closure. We evaluated the efficacy and safety of LAA closure in a consecutive series of non-valvular atrial fibrillation patients with contraindications to long-term oral anticoagulation or at high bleeding risk. METHODS AND
results101 consecutive non-valvular atrial fibrillation patients (age 74.7 ± 7.5 years) at high risk for stroke (CHA2DS2-VASc Score 4.4 ± 1.6) and high bleeding risk (HAS-BLED Score 4.2 ± 1.3) received LAA closure with either the Watchman closure device (n = 38) or the Amplatzer cardiac plug (n = 63). Dual antiplatelet therapy with aspirin and clopidogrel was recommended for 3-6 months after device implantation, followed by long-term antiplatelet therapy with aspirin. No anticoagulation was given after device implantation. Mean follow-up was 400 days. One patient (1 %) experienced a transient ischemic attack, and two patients (2 %) suffered from ischemic stroke. While on recommended antiplatelet therapy, bleeding occurred in 12/101 patients (12 %). Bleeding was significantly reduced with 3 compared with 6 months dual antiplatelet therapy (3.0 vs. 16.2 %, p < 0.05) while ischemic or thrombotic events were similar.
conclusionLeft atrial appendage closure in patients with non-valvular atrial fibrillation and high risk for stroke and bleeding events effectively prevented stroke and reduced cerebral ischemic events compared to expected stroke rate according to CHA2DS2-VASc Score. Dual antiplatelet therapy for 3 months reduced the rate of bleeding events compared to 6 months therapy with no increase of thrombotic events.
