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

objectivePathogenic mutations in GRIN2B are an important cause of severe neurodevelopmental disorders resulting in epilepsy, autism, and intellectual disability. GRIN2B encodes the GluN2B subunit of N-methyl-d-aspartate receptors (NMDARs), which are ionotropic glutamate receptors critical for normal development of the nervous system and synaptic plasticity. Here, we characterized a novel Grin2b heterozygous knockout rat model with electroencephalography (EEG) and pharmacological interventions to block spontaneous seizures.

methodsThrough western blot analysis we assessed the extent of GluN2B protein knockdown in knockout (Grin2b

resultsCompared to wild-type rats, Grin2b SIGNIFICANCE: Our data show that the new rat Grin2b haploinsufficiency model exhibits clinically relevant phenotypes and highlights two potential therapeutic options for GRIN2B-related epilepsy.
