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

Amyotrophic lateral sclerosis (ALS) is a fatal and incurable neurodegenerative disease characterized by the progressive loss of motor neurons in the spinal cord and brain. In particular, autosomal dominant mutations in the superoxide dismutase 1 (SOD1) gene are responsible for ~20% of all familial ALS cases. The clustered regularly interspaced short palindromic repeats (CRISPR)-CRISPR-associated (Cas9) genome editing system holds the potential to treat autosomal dominant disorders by facilitating the introduction of frameshift-induced mutations that can disable mutant gene function. We demonstrate that CRISPR-Cas9 can be harnessed to disrupt mutant SOD1 expression in the G93A-SOD1 mouse model of ALS following in vivo delivery using an adeno-associated virus vector. Genome editing reduced mutant SOD1 protein by >2.5-fold in the lumbar and thoracic spinal cord, resulting in improved motor function and reduced muscle atrophy. Crucially, ALS mice treated by CRISPR-mediated genome editing had ~50% more motor neurons at end stage and displayed a ~37% delay in disease onset and a ~25% increase in survival compared to control animals. Thus, this study illustrates the potential for CRISPR-Cas9 to treat SOD1-linked forms of ALS and other central nervous system disorders caused by autosomal dominant mutations.
