Description of Copy Number Variations in a Series of Children and Adolescents with FASD in Reunion Island.
Article in Children (Basel, Switzerland), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundFetal Alcohol Spectrum Disorders (FASD) are the most common cause of neurocognitive impairment and social inadaptation, affecting 1 birth in 100. Despite the existence of precise diagnostic criteria, the diagnosis remains difficult, often confounded with other genetic syndromes or neurodevelopmental disorders. Since 2016, Reunion Island has been a pilot region for the identification, diagnosis, and care of FASD in France.
objectiveTo evaluate the prevalence and the types of Copy Number Variations (CNV) in FASD patients.
methodsA retrospective chart review of 101 patients diagnosed with FASD in the Reference Center for developmental anomalies and in the FASD Diagnostic Center of the University Hospital was performed. Records of all patients were reviewed to obtain their medical history, family history, clinical phenotype, and investigations, including genetic testing (CGH- or SNP-array).
resultsA rate of 20.8% (n = 21) of CNVs was found including 57% (12/21) of pathogenic variants and 29% (6/21) of variants of uncertain signification (VUS).
conclusionA particularly high number of CNVs was found in children and adolescents with FASD. It reinforces the plea for a multidisciplinary approach for developmental disorders to explore both environmental factors, such as avoidable teratogens and intrinsic vulnerabilities, especially genetic determinants.
