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

L-2-hydroxyglutaric aciduria (L-2-HGA, #236,792) is an autosomal recessive neurodegenerative disorder caused by the deficiency of L-2-hydroxyglutarate dehydrogenase, a flavin adenine dinucleotide (FAD)-dependent enzyme, due to biallelic pathogenic variants in the L2HGDH gene. The present study described the patient with L2HGA presenting with a slight psychomotor delay, epilepsy from 5 years of age, non-progressive cerebellar ataxia, and mild to moderate intellectual disability during 10 years of follow-up. Two different heterozygous variants in the L2HGDH gene were identified in the patient: a known substitution c.829C > T(p.Arg277*) and a novel substitution c.1196 + 1G > A corresponding with significantly increased urinary L-2-hydroxyglutarate (L2HG) excretion. A 6-month period of treatment with riboflavin (100 mg/day) was implemented with no clinical nor biochemical effect.
