Meningeal null cell lymphoma causing diffuse pachymeningeal contrast enhancement in a dog.
Article in The Journal of small animal practice, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Diffuse pachymeningeal contrast enhancement is an uncommon imaging finding in dogs and current understanding of its aetiologies in veterinary medicine is limited. A 2-year-old female neutered Pug presented with chronic progressive vestibular signs, facial nerve paralysis, obtundation and episodic decerebellate rigidity. A magnetic resonance imaging study of the head revealed diffuse pachymeningeal thickening and contrast enhancement involving the caudal fossa and falx cerebri. Cerebrospinal fluid analysis revealed marked neutrophilic pleocytosis. Infectious disease testing was negative and a tentative diagnosis of intracranial idiopathic hypertrophic pachymeningitis was made. Immunosuppressive treatment resulted in a short period of clinical improvement. The patient subsequently suffered multiple relapses which failed to respond to alternative immunosuppressive strategies, necessitating euthanasia. Histopathological findings supported a meningeal null cell lymphoma. While rare, neoplastic causes of diffuse pachymeningeal thickening and contrast enhancement should be considered.
