Getting de Pointes Across: Isoproterenol for Refractory Methadone-Associated Torsades de Pointes in Alcohol Withdrawal.
Article in Cureus, 2026. 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
Methadone is known to prolong the QTc interval and may precipitate torsades de pointes (TdP), particularly at higher doses and in the presence of additional risk factors. Standard management involves discontinuation of the offending agent, correction of electrolyte imbalances, and administration of intravenous magnesium; however, some patients may continue to experience recurrent TdP. We present a case of a young female on high-dose methadone, who developed TdP in the context of acute alcohol withdrawal and clonidine-associated bradycardia. Her arrhythmia persisted despite treatment with magnesium and lidocaine but resolved following initiation of an isoproterenol infusion. This case emphasizes the importance of systematic risk assessment in patients receiving methadone and supports the use of isoproterenol as a viable therapeutic option when TdP is refractory to first-line interventions.
