Case Report: acute and long-term effects of a massive beta-mercaptoethanol inhalation.
Article in Frontiers in toxicology, 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
Introduction: β-mercaptoethanol is widely used in biochemistry and industrial applications. Animal toxicity has been demonstrated but very limited data exists regarding its human effects. Case Description: A 40-year-old male patient was exposed to β-mercaptoethanol vapours after an accidental occupational spillage. He developed dizziness, blurred vision, a headache and epistaxis within minutes alongside dyspnoea and cough in the following hours. Lung function tests displayed bronchial hyperreactivity and increased resistances, consistent with a reactive airways dysfunction syndrome. Neuropsychological testing showed memory difficulties affecting both working and long-term verbal memory, together with attentional and executive weaknesses. Twenty months after the incident, the patient still experienced memory impairment and dyspnoea while bronchial hyperreactivity remained present. Conclusion: Respiratory exposure to large quantities of β-mercaptoethanol vapours can cause reactive airways dysfunction syndrome and is associated with long-term neurological and respiratory symptoms.
