A Case Report of Encephalopathy With Myoclonus: A Rare Neurologic Side Effect of Ranolazine.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
The evaluation of the cause of an acute encephalopathy can be challenging due to nonspecific presentations and many potential etiologies. Ranolazine-induced encephalopathy has seldom been reported in the literature. We report a case of ranolazine-induced encephalopathy with myoclonus. A 78-year-old male with past medical history of coronary artery disease (CAD) with refractory angina on ranolazine, chronic kidney disease (CKD) stage III, multiple other medical comorbidities presented to the hospital after a fall and complaints of generalized weakness. The patient, during admission, developed encephalopathy and generalized myoclonus that resolved by stopping ranolazine. Acute encephalopathy has a wide differential diagnosis. The association of myoclonus and bilateral asterixis favors a systemic metabolic process or a circulating factor. It is essential in workup that close attention be paid to medication review as patients with liver and/or kidney dysfunction can become toxic on routine medication doses. This case signifies the importance of medication review and highlights ranolazine as a potential cause of acute encephalopathy with myoclonus.
