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

Most Beckwith-Wiedemann syndrome (BWS) cases are sporadic; nonetheless, imprinting center 1 (IC1) microdeletions have been suggested as a rare cause of familial BWS, with ~ 20 reported cases. We report 13 cases from nine families with IC1 microdeletions. Recurrent 1.4-kb, 1.8-kb, and 2.2-kb deletions were observed. IC1 hypermethylation was identified in all families, and we established a statistically significant relationship between IC1 microdeletions and hypermethylation (OR: 108.17, p = 2.76e-13). This study confirms IC1 microdeletions as a cause of familial BWS, expands the understanding of their molecular mechanisms, and supports a Likely Pathogenic clinical classification for IC1 microdeletions.
