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

Complex neurodevelopmental disorders such as autism spectrum disorders (ASD) and schizophrenia are characterized by impaired social interactions, cognitive deficits, and repetitive behaviors. Genome-wide association studies (GWAS) have identified the α5 nicotinic acetylcholine receptor (α5-nAChR) subunit as a significant risk factor for these neuropsychiatric conditions. The α5 subunit is a critical modulator of neural circuit dynamics, specifically through its functional involvement within vasoactive intestinal peptide (VIP)-positive interneurons; however, its role in the sex-dependent maturation of behavioral phenotypes remains poorly understood. We characterized α5-nAChR knockout (ACNA5) mice to investigate the neurodevelopmental consequences of α5 subunit loss. ACNA5 mice displayed sexually dimorphic and age-dependent core symptoms relevant to ASD and schizophrenia. Regarding anxiety-like behavior, there was an opposite sex pattern between genotypes, evident only in adulthood. Cognitive assessment using the novel object location task revealed early-onset spatial memory deficits in ACNA5 females, whereas males exhibited a progressive decline from adolescence to adulthood. In the social domain, adult ACNA5 mice failed to exhibit social novelty preference; females displayed complete social indifference, while males displayed a pronounced familiarity bias. In addition, ACNA5 mice of both sexes displayed amplified repetitive behavior, emerging earlier in males, and poor nest-building scores across developmental stages. Together, these findings identify the α5-nAChR subunit as a crucial modulator of the maturation of neural circuits underlying social motivation, cognition, and emotional regulation. Our results implicate α5-containing nicotinic receptors in the pathogenesis of neurodevelopmental disorders and establish the ACNA5 mouse as a valuable model for investigating sex-specific developmental trajectories and therapeutic windows.
