Overlap of severe hypokalaemia and Guillain-Barré syndrome following Salmonella infection: a rare double etiology of acute lower limb paralysis - case report.
Article in BMC infectious diseases, 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
This case highlights hypokalaemia and Guillain–Barré syndrome as rare and serious complications of Salmonella infection.A 25-year-old woman was admitted to the emergency department with neuropathic pain, paraesthesia, paraparesis and circulatory shock associated with salmonella infection and severe hypokalaemia. Despite prompt and adequate correction of hypokalaemia, the neuropathic pain and paresis persisted, raising concern for other differential diagnosis, such as Guillain-Barré syndrome (GBS). Therefore, further neurological workups were performed to evaluate this condition. After intravenous immunoglobulin (IVIG) treatment, the patient finally showed significant improvement on day 12 of admission.The rare association of GBS and hypokalaemia following Salmonella infection represents a clinical and diagnostic challenge. Clinicians should remain alert to the potential overlap between electrolyte imbalances and neuromuscular disorders.
