Possible Factor Xa Resistance in a Patient Who Failed Apixaban and Rivaroxaban.
Article in Clinical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
This article aims to discuss the literature on switching to an anticoagulant with a different mechanism of action in case of treatment failure. We present a patient with atrial fibrillation who incurred an embolic stroke despite adequate anticoagulation with apixaban and developed a new symptomatic ischemic stroke during the same admission after switching to rivaroxaban, a factor Xa inhibitor with a similar mechanism of action. He had no new events at 3-months after switching to dabigatran, a direct thrombin inhibitor. We identified no apparent reason for anticoagulation failure in our patient. The literature on switching anticoagulants in case of failure is inconclusive with no strong supportive evidence. More research is needed to define anticoagulation failure and identify cases with factor Xa inhibitor resistance, in which switching to a different mechanism of anticoagulation may be appropriate.
