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

BACKGROUND/

objectivesA Petit Bleu de Gascogne (PBDG) dog presented with a progressive neurological disorder characterized by hind-limb weakness, anxiety and hallucinatory episodes, lip smacking, progressive vision loss, muscle atrophy, and ataxia. Magnetic resonance imaging revealed diffuse brain atrophy. The dog was euthanized at approximately 23 months of age due to the progression of neurological signs. A study was undertaken to identify the molecular genetic basis of the disorder in this dog.

methodsMicroscopic analyses were performed to characterize the disease pathology and whole-genome sequencing was performed to identify the molecular genetic basis of the disorder.

resultsThe proband exhibited pronounced accumulations of autofluorescent intracellular inclusions in the brain, retina, and heart with ultrastructural appearances similar to those of lysosomal storage bodies that accumulate in the neuronal ceroid lipofuscinosis (NCLs), a group of progressive neurodegenerative disorders. Whole-genome sequence analysis of DNA from the proband identified homozygous missense variants in

conclusionsThese findings raise the possibility that the disease involves the combined influence of the two variants, and that the proteins encoded by these genes interact within the Golgi apparatus to mediate protein sorting and transport to lysosomes. An alteration in this interaction could underlie the NCL-like lysosomal storage disorder observed in the proband.
