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: 16p13.11 microduplication syndrome is a rare genomic disorder caused by an extra copy of a small segment of DNA on the short arm of chromosome 16 at a specific location in band 13.11. The clinical presentation is highly variable. Some individuals are entirely asymptomatic, while others present with a spectrum of neurodevelopmental disorders. Case Description: We report two cases with 16p13.11 microduplication to investigate the genotype-phenotype correlations. Peripheral blood was collected from the two patients and their respective parents and all participants underwent whole exome sequencing. Bioinformatics analysis and pathogenicity assessment were performed for variants as well as next-generation sequencing coverage depth analysis to identify abnormal copy number regions. As a result, a 0.893 Mb duplication of 16p13.11 region (chr16:15380928-16274075) was identified in patient 1, while his father carried a 0.841 Mb duplication in the same region (chr16: 15380928-16221831). In Patient 2, a 1.39 Mb duplication of 16p13.11 region (chr16: 14927699-16317333)-inherited from his father-was identified, as well as a pathogenic heterozygous variant in Conclusions: Our findings underscore the highly incomplete penetrance and phenotypic variability of 16p13.11 microduplication. Future research should focus on the pathogenic mechanisms, explore potential interactions with genes like
