1 · What the graph read from 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.

2 · The registry

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

backgroundThe usefulness of dabigatran etexilate for the prevention of stroke in patients with atrial fibrillation (AF) has been reported.

objectivesIn this study the efficacy and safety of dabigatran etexilate for anticoagulation for AF ablation were examined.

methodPatients were divided into three groups: Group 1, interrupted warfarin bridged by heparin between pre- and post-ablation; Group 2, continuous warfarin therapy; and Group 3, dabigatran etexilate therapy. Anticoagulation therapy with warfarin or dabigatran etexilate was performed from 30 days before to at least 90 days after AF ablation. Dabigatran etexilate was administered at 110 or 150 mg twice daily, depending on renal function and age.

resultsPatients' clinical characteristics, associated disorders, echocardiographic parameters and arrhythmia status were not different among the three groups. Procedural parameters such as procedural time and radiofrequency energy supply were also not different among the three groups. The dabigatran etexilate group and the warfarin groups had no embolic complications (stroke, cerebral transient ischaemic attack, deep venous thrombosis or pulmonary embolism). No pericardial tamponade was observed in the dabigatran etexilate group, while two patients in each of Group 1 (2/194, 1.0 %) and Group 2 (2/203, 0.98 %) developed cardiac tamponade, though the differences were not significant. Pericardial effusion and groin haematoma were observed in one patient each (1/105, 0.9 %) in the dabigatran etexilate group, and the incidences were not different from the warfarin group (Group 1: 4/194, 2.1 % and 2/194, 1.0 %; Group 2: 3/203, 1.5 % and 2/203, 1.0 %, respectively). As a whole, the safety outcomes did not differ among the three groups.

conclusionDabigatran etexilate is an effective and safe anticoagulation therapy for AF ablation. Thus, dabigatran etexilate appears to be useful as an alternative anticoagulant therapy to warfarin for AF ablation.
