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

Canine degenerative myelopathy (DM) has been associated with mutations in the superoxide dismutase 1 gene (SOD1). Although the SOD1:c.118G>A mutation has been identified in Boston terriers and French bulldogs, no histological-confirmed degenerative myelopathy has been reported in either breed. An 8-year-old male neutered Boston terrier-French bulldog mixed breed dog was presented with T3 to L3 myelopathy. Magnetic resonance imaging (MRI) of the spinal cord and cerebrospinal fluid analysis were unremarkable. DNA testing revealed homozygosity for the SOD1:c.118G>A mutation. Despite supportive treatment, the dog continued to progress over 37 months. Post mortem full spine MRI study found severe spinal cord and epaxial muscle atrophy. The diagnosis of DM was confirmed by histopathology and positive immunohistochemical staining with anti-SOD1 antibodies. This case report documents the clinical and imaging progression of DM in a Boston terrier-French bulldog mixed breed.
