1 · What the graph read from it

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.

2 · The registry

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

Cerebellar ataxia, neuropathy and vestibular areflexia syndrome (CANVAS) is a recently recognised but underdiagnosed cause of late-onset hereditary ataxia. Symptoms may vary, and differential diagnoses can span several specialties. We report the case of a man in his 60 s who presented with a 10 year history of imbalance and progressive gait disturbance associated with a chronic spasmodic cough that preceded these symptoms by almost 30 years. He had previously undergone extensive testing for acquired and genetic causes of ataxia without a conclusive diagnosis. Brain MRI revealed cerebellar atrophy, and nerve conduction tests suggested a sensory ganglionopathy. Vestibular function testing was crucial for diagnosis, identifying a severe bilateral vestibulopathy. This led to the consideration of CANVAS, which was finally confirmed by genetic testing. This case raises awareness of this novel genetic disease, highlighting the importance of objective vestibular function tests in establishing an early diagnosis.
