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

Mitochondrial aminoacyl-tRNA synthetases (mt-aaRSs) are a family of enzymes that play critical roles in protein biosynthesis. Mutations in mt-aaRSs are associated with various diseases. As a member of the mt-aaRS family, PARS2 encoding prolyl-tRNA synthetase 2 was recently shown to be associated with Alpers syndrome and certain infantile-onset neurodegenerative disorders in four patients. Here, we present two patients in a pedigree with early developmental delay, epileptic spasms, delayed myelination combined with cerebellar white matter abnormalities, and progressive cortical atrophy. Whole-exome sequencing revealed pathogenic compound heterozygous variants [c.283 G > A (p.95 V > I)] and [c.604 G > C (p.202 R > G)] in PARS2. Nearly all patients had epileptic spasms with early response to treatment, early developmental delay and/or regression followed by generalized hypotonia, postnatal microcephaly, elevated lactate levels, and progressive cerebral atrophy. Our study provides further evidence for validating the role of PARS2 in the pathology of related infantile-onset encephalopathy, contributing to the phenotypic features of this condition, and providing clinical and molecular insight for the diagnosis of this disease entity.
