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

A 10-month-old domestic shorthair kitten was evaluated for progressive neurological dysfunction characterized by ataxia, episodic opisthotonus, impaired vision, dysphagia and seizures. Clinicopathological findings included marked hypocobalaminemia and abnormal concentrations of urinary methylmalonic acid, methylcitrate, and propionylglycine. Magnetic resonance imaging revealed generalized cerebral and cerebellar atrophy, with mild ventriculomegaly. Despite dietary modification, cobalamin supplementation, antiepileptic therapy, neurological deterioration progressed, culminating in refractory seizures and euthanasia. Post-mortem examination revealed multiorgan and central nervous system changes, characterized by neuronal degeneration and necrosis, cortical atrophy, globular eosinophilic intracytoplasmic material within neurons and gliosis. Methylmalonic aciduria is a rare metabolic disorder resulting from defects in cobalamin metabolism or methylmalonyl-CoA mutase activity.
