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

The goal of this paper is to review literature on the topic of anticoagulation resumption after stroke from atrial fibrillation. Following ischemic stroke, the average annual risk of recurrent stroke in a patient with a CHADS2 score of 9 is 12.2%%, translating to an average daily risk of 0.03%%. Oral anticoagulant therapy provides a 75% relative risk reduction. However, in the 2-week period immediately following an acute stroke, this daily risk appears to be elevated. The same period is associated with an increased risk of hemorrhagic transformation of ischemic stroke due to reperfusion, impaired autoregulation, and disruption of the blood-brain barrier. Use of thrombolytics and anticoagulants, baseline infarct size, presence of microhemorrhages, and evidence of hemorrhagic transformation further increases the risk of symptomatic hemorrhagic. The decision to resume anticoagulation early after ischemic stroke from atrial fibrillation must carefully balance the risks of hemorrhagic transformation with the risk of recurrent stroke. There are currently 4 trials in progress at present (OPTIMAS, ELAN, TIMING, and START) comparing different anticoagulant resumption protocols after stroke in patients on non-vitamin K oral anticoagulants. There are a number of major limitations of the studies to date on the timing of anticoagulation resumption on stroke in atrial fibrillation. For instance, they do not explicitly account for infarct size, presence/absence of hemorrhagic transformation, recanalization via mechanical thrombectomy, and bleeding diatheses such as liver synthetic dysfunction or thrombocytopenia. These factors are crucial in personalizing a treatment decision to an individual patient.
