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/

objectivesDilated cardiomyopathy (DCM) is characterized by heart failure and cardiac dilation, distinguishing it from ischemic and non-ischemic heart diseases. To date, more than 50 genes have been identified as being associated with DCM. Mutations in the Bcl-2-associated athanogene 3 (BAG3) gene (NM_004281.4) play a significant role in DCM pathogenesis. However, further investigation is required for comprehensive screening of BAG3 gene mutations. The identification of BAG3 mutations is crucial for diagnosing DCM and elucidating its molecular mechanisms.

methodsTo detect DCM-related gene mutations in the proband, next-generation sequencing was performed on DNA samples, with results subsequently confirmed through Sanger sequencing.

resultsA novel duplication frameshift mutation, c.633dup (p.His212ThrfsTer43), was identified within exon 3 of the BAG3 gene in a patient diagnosed with DCM.

conclusionsThe detection of a novel duplication frameshift mutation, c.633dup, in the BAG3 gene contributes to the expanding knowledge of BAG3 mutations.
