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 and Objectives: Periventricular nodular heterotopia (PNH) is a neuronal migration disorder caused by the failure of neurons to migrate properly to the cerebral cortex, characterized predominantly by epilepsy. Most PNH cases are associated with variants in Methods: Whole-exome sequencing (WES) was performed on genomic DNA isolated from the peripheral blood. Mosaicism levels were quantified using droplet digital PCR (ddPCR), transcriptomic alterations were analyzed by RNA sequencing (RNA-seq), and splicing defects were investigated via a minigene splicing assay. Results: WES analysis identified a novel splicing variant (NM_001110556.2: c.4599-2A > G) in the Discussion: This study expands the phenotypic and genetics spectrum of PNH and demonstrates a dual PNH phenotype with a bi-transcript mechanism. It also provides clinical evidence of mosaic inheritance and tissue-specific mosaicism, offering valuable implications for genetic counseling and prenatal diagnosis.
