Major Complications Associated With Cerebrospinal Fluid Collection in 11 Dogs: Clinical Presentation and Imaging Characteristics.
Article in Journal of veterinary internal medicine. 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
backgroundCerebrospinal fluid (CSF) collection is routinely performed in dogs with neurological disorders. Little is known about the rate of major complications associated with CSF collection.
objectivesDetermine the number of dogs experiencing a major complication secondary to CSF collection in a single referral hospital. ANIMALS: Eleven dogs.
methodsSingle-center, retrospective description of the number and nature of major complications encountered during or after CSF collection in dogs.
resultsFrom 7545 CSF collections performed between 1998 and 2024, 11 dogs (0.15%) experienced a major complication. Eight of these dogs had abnormal mentation on presentation. The most common neuroanatomical localization was multifocal (5/11). Nine dogs underwent magnetic resonance imaging (MRI) of the head and one dog had radiographs of the cervical vertebral column before CSF collection. The most common MRI findings included effacement of the cerebral sulci (7/9) and dilatation of the ventricular system (5/9). Cerebrospinal fluid collection was performed in 11 dogs, of which 3 were unsuccessful. Analysis of CSF aided in the diagnosis of meningoencephalitis of unknown origin (3/8), cryptococcosis (1/8), lymphoma (1/8), and results were normal in one and non-specific in two dogs. Eight dogs were euthanized after failure to recover spontaneous ventilation (6), cardiopulmonary arrest (1) or severe neurological deterioration (1). One dog died during cardiopulmonary resuscitation. Repeat MRI after CSF collection identified caudal transtentorial and foramen magnum herniation in one dog. Two dogs survived to hospital discharge but with permanent neurological deficits.
conclusionThe frequency of major complications following CSF collection was low, but the associated mortality was high. Abnormal mentation and MRI evidence of cerebral cortical swelling were commonly detected before CSF collection in dogs experiencing complications.
