Inhalation arsine poisoning: clinical features and treatment experience of 12 cases from a single incident.
Article in BMC pharmacology & 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
backgroundArsine poisoning is a rare but life-threatening condition characterized by severe hemolysis. Clinical data on its management remain limited. This study describes the clinical features, diagnostic approach, and treatment experience of 12 patients from a single arsine poisoning incident.
methodsClinical data from the 12 patients were retrospectively collected. Presenting symptoms, diagnostic findings, and treatment strategies were summarized.
resultsTen of the 12 patients survived. Arsenic was detected in cleaning wastewater and in the red blood cells of four patients, and, together with clinical hemolysis, supported the diagnosis of arsine poisoning. Common symptoms included headache, nausea, vomiting, abdominal pain, dizziness, chest tightness, and hematuria; headache, nausea, and vomiting frequently co-occurred. All patients received high-dose methylprednisolone, vitamin C + B6, and chelation therapy. The two non-survivors additionally received mechanical ventilation, therapeutic plasma exchange, dialysis, methylene blue, and transfusions; they died on day 3 from progressive cardiovascular failure secondary to acute hemolysis. Five other patients underwent therapeutic plasma exchange and dialysis and ultimately survived.
conclusionsThis case series highlights the clinical presentation, diagnostic workflow, and management of arsine poisoning in a well-characterized patient cluster. Early recognition and timely intervention may facilitate clinical management. The findings are descriptive and limited by the retrospective design and small sample size.
