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

backgroundNon-vitamin K antagonist oral anticoagulants (NOACs) are at least non-inferior to Vitamin K Antagonists (VKAs) for stroke prevention on patients with non-valvular atrial fibrillation (AF). We aimed to evaluate the efficacy and safety of NOACs in patients undergoing cardioversion through a systematic review and meta-analysis.

methodsMEDLINE, Cochrane Library, and Web of Science(®) databases (until September 2014) were searched for studies fulfilling inclusion criteria. Two reviewers independently selected randomized controlled trials (RCTs) evaluating NOACs and VKA in patients with AF undergoing cardioversion. The primary outcome was ischemic stroke or systemic embolism (IS/SE). Secondary outcomes were major bleeding, myocardial infarction, and mortality. Risk ratio (RR) and 95 % confidence intervals were derived through random-effects meta-analysis. Heterogeneity was evaluated through I (2) test.

resultsFour RCTs (3 post-hoc analysis) evaluating apixaban, dabigatran, and rivaroxaban in 3,512 patients with AF were included. The risk of IS/SE with NOACs was similar to VKA (RR 0.60, 95 % CI 0.20-1.80; I (2) = 17 %). There was no significant increase in major bleeding (RR 1.27, 95 % CI 0.58-2.81; I (2) = 0 %), myocardial infarction (RR 0.71, 95 % CI 0.10-5.04; I (2) = 0 %), or mortality (RR 0.87, 95 % CI 0.24-3.08; I (2) = 0 %) with NOACs.

conclusionsThis systematic review and meta-analysis suggests that NOACs may be as safe as VKAs in the setting of AF cardioversion.
