Copy number variants and their implications for developmental and behavioural problems in cleft lip and/or palate.
Article in Human molecular genetics, 2025. 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
Cleft lip and/or palate (CL/P) is the most common craniofacial congenital anomaly and has been associated with higher risk of neurodevelopmental and behavioural problems indicating potential shared genetic factors between CL/P and neurodevelopmental disorders. In this study, we aimed to determine the prevalence of neurodevelopmental copy number variants (CNV) in children with CL/P and their link to early developmental and behavioural problems. Using data from the Cleft Collective, the largest UK-based national cohort study of children with CL/P, we determined the rates of neurodevelopmental CNVs in children with CL/P comparing them to the general population, explored differences by cleft type and investigated risk of developmental delays and behavioural problems among those with CL/P and neurodevelopmental CNVs. Children with CL/P had a higher prevalence of neurodevelopmental CNVs than participants in four population-based samples (3.7% vs 2.3% in the Avon Longitudinal Study of Parents and Children (ALSPAC), 2.0% in Born in Bradford (BiB), 2.3% in Millenium Cohort Study (MCS), 1.7% in UK Biobank, ORs(95%CIs): ALSPAC = 1.56(1.18-2.06), BiB = 1.84(1.37-2.45), MCS = 1.59(1.19-2.11), UK Biobank = 2.15(1.68-2.71). Children with cleft palate only were 3 times more likely to have a neurodevelopmental CNV (95%CIs1.50-6.59, p = 0.03) than children with cleft lip only. Furthermore, children with CL/P and neurodevelopmental CNVs were more likely to experience early developmental delays and behavioural problems by age 5 compared to children with CL/P and without neurodevelopmental CNVs. These findings highlight that genetic testing ascertaining the presence of neurodevelopmental CNVs might be helpful in early identification of developmental needs in children with CL/P.
