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

Von Hippel-Lindau syndrome (VHL) is an autosomal dominant disorder characterized by the development of tumors and cysts in multiple organs. Pathogenic variants in VHL are known to be associated with the development of this syndrome. Therefore, the present study aimed to investigate VHL rearrangements in a family with VHL syndrome. In the proband, who presented with retinal hemangioma, whole exome sequencing (WES) revealed significant genetic variation. However, WES did not detect germline deletion in VHL in the proband's son. Furthermore, multiplex ligation-dependent probe amplification (MLPA)-next-generation sequencing (NGS) analysis showed that the genomes of the proband and her son encompassed a deletion in VHL, extending from exon 2 to exon 3. Via increasing the probe density to gradually approach the breakpoint and following Sanger sequencing analysis, it was verified that an intermediate fragment of 6,662 bp was lost, with a reconnection occurring between chromosome 3:10145434 and 10,152,097 (GRCh38/hg38). Overall, the present study demonstrated that the application of MLPA-NGS technology combined with Sanger sequencing could be employed to precisely locate deleted DNA ‌fragments.
