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

purposeSensory dysfunction is highly prevalent in individuals with ASD. Olfactory abnormalities in ASD remain under-explored. The present study aimed to examine olfactory identification, memory and metacognition in children with ASD.

methodsFifty children with ASD (aged 7–10 years) and fifty age- and sex-matched controls were enrolled. Olfactory identification ability was assessed with the Universal Sniff (U-Sniff) test, and olfactory memory ability with a modified U-Sniff test. Olfactory metacognition was assessed using the Children’s Personal Significance of Olfaction (ChiPSO), the Body Odor Sniffing Questionnaire (BOSQ) and the Chemosensory Pleasure Scale for Children (CPS-C).

resultsResults revealed that participants with ASD exhibited atypical olfactory identification, memory and metacognition abilities compared to typically developing controls. Additionally, both olfactory identification and metacognition were significantly associated with social deficits (evaluated by the Social Responsiveness Scale-2 and the Autism Spectrum Quotient-Children’s version) in the ASD group.

conclusionsThese findings highlight the importance of studying olfactory dysfunction as a key sensory aspect in ASD, providing insights into the link between olfactory processing impairments and social deficits in the disorder.
