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

Background: 15q11.2-q13 duplication syndrome (Dup15q; OMIM #608636) is a rare neurodevelopmental disorder. While interstitial duplications (copy number = 3) are relatively well characterized, contiguous rearrangements comprising both tetrasomic (copy number = 4) and adjacent trisomic (copy number = 3) segments are rare. We report a Chinese girl with a Case Presentation: The patient was born at 35+2 weeks of gestation and presented with global developmental delay, severe autism spectrum disorder (CARS: 44), and profound cognitive and language impairment (GQ 30, GMQ 57 at 2 years 4 months). Brain MRI demonstrated delayed myelination, and magnetic resonance spectroscopy showed metabolic abnormalities in the left frontal lobe. Video-electroencephalography at 3 years of age revealed sleep-activated frontocentral epileptiform discharges without clinical seizures. Trio whole-genome sequencing with copy number variation analysis identified a Conclusion: This case expands the genomic spectrum of complex proximal 15q rearrangements and highlights the value of high-resolution genomic testing for resolving complex neurodevelopmental disorders. It also emphasizes that severe genetic etiologies may be overlooked when developmental abnormalities are initially attributed to prematurity. These findings support early comprehensive genomic evaluation in children with profound developmental delay, autism spectrum disorder, or persistent developmental impairment despite conventional rehabilitation.
