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

objectiveOur study investigates the impact of junction breakpoints of complex chromosomal rearrangements (CCRs) on developmental delay and intermittent epilepsy in children, aiming to elucidate the underlying genetic mechanisms.

methodsWe reported a patient with developmental delay in family 1, and we reported a patient with intermittent epileptic seizures in family 2. Karyotype analysis was used to detect chromosomal abnormalities. Whole exome sequencing (WES) and/or whole genome sequencing (WGS) can further assist in identifying the genetic etiology.

resultsOur findings revealed a central inversion rearrangement on chromosome 3 affecting the Roundabout Guidance Receptor 1 (ROBO1), DnaJ Heat Shock Protein Family Member C13 (DNAJC13), and Acyl-CoA Dehydrogenase Family Member 11 (ACAD11) genes in patient 1, suggesting its potential pathogenic role in developmental delays. In another patient, we identified a complex rearrangement involving chromosome 1, coupled with a heterozygous mutation in KCNA2 NM_004974.4:c.347A>C (p.Tyr116Ser), indicating a strong association with intermittent seizures.

conclusionsCombining chromosome karyotype analysis with WES and/or WGS can accurately locate chromosomal breakpoints and provide more accurate genetic information. It is an important approach for integrated diagnosis.
