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

Purpose: Clinical scoring systems have been developed (e.g., CHA2DS2-VASc and HAS-BLED) to aid in the perioperative management of anticoagulation therapy. The decision to continue, modify, or stop anticoagulation prior to surgical procedures requires multidisciplinary input and an individualised plan. Decisions both to continue or reverse anticoagulation can cause visual loss. Observations: We report the use of andexanet alfa (recombinant inactive factor Xa) as a reversal agent for anticoagulation in atrial fibrillation after surgical bleeding, which resulted in secondary homonymous hemianopsia and ischemic infarct. Conclusion and importance: Stroke is a major risk factor for atrial fibrillation, and anticoagulation in specific settings is evidence-based. Anticoagulation, however, increases the risk of haemorrhage and may require the use of a reversal agent (e.g., Andexanet alfa) in cases of severe bleeding. Unfortunately, reversal of anticoagulation in this setting can lead to an ischemic stroke and visual loss.
