Iatrogenic botulinum Toxin Type A poisoning with persistent unilateral vocal cord paralysis: a case report and clinical implications.
Article in Frontiers in pharmacology, 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
With the continuous advancement of medical aesthetic technologies, botulinum toxin injection has emerged as a prevalent method for wrinkle removal and facial enhancement. However, improper administration can result in botulism incidents. This article presents a case of poisoning caused by the facial injection of Botulinum Toxin Type A. The patient was successfully treated through comprehensive measures, including the administration of Botulinum Antitoxin Type A, neurotrophic therapy, and functional rehabilitation; however, unilateral vocal cord paralysis persisted. This case underscores the potential for severe complications, such as vocal cord paralysis, arising from improper injections of Botulinum Toxin Type A. Additionally, this article reviews the existing literature concerning vocal cord paralysis.
