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

Barth syndrome is an X-linked cardiomyopathy with neutropenia and 3-methylglutaconic aciduria. Recently, mutations in the G4.5 gene, located in Xq28, have been described in four probands with Barth syndrome. We have now evaluated 14 Barth syndrome pedigrees for mutations in G4.5 and have identified unique mutations in all, including four splice-site mutations, three deletions, one insertion, five missense mutations, and one nonsense mutation. Nine of the 14 mutations are predicted to significantly disrupt the protein products of G4.5. The occurrence of missense mutations in exons 3 and 8 suggests that these exons encode essential portions of the G4. 5 proteins, whose functions remain unknown. We found no correlation between the location or type of mutation and any of the clinical or laboratory abnormalities of Barth syndrome, which suggests that additional factors modify the expression of the Barth phenotype. The characterization of mutations of the G4.5 gene will be useful for carrier detection, genetic counseling, and the identification of patients with Barth syndrome who do not manifest all of the cardinal features of this disorder.
