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

Mutations in the genes encoding the subunit polypeptides of the alpha6beta4 integrin (ITGA6 and ITGB4, respectively) have been previously demonstrated in patients with a lethal form of epidermolysis bullosa with congenital pyloric atresia (OMIM #226730). In this study, we demonstrate for the first time ITGB4 mutations in nonlethal phenotype of epidermolysis bullosa with congenital pyloric atresia. Specifically, the proband was shown to be a compound heterozygote for a missense mutation (L156P) and a nonsense mutation (R554X). The leucine substitution by proline was shown to affect a residue, which was precisely conserved in different human, rodent, and drosophila integrin-beta polypeptides, and consequently disrupts the alpha-helix formation of the polypeptide segment as determined by Garnier alpha-helicity plot. The nonsense mutation in another allele was accompanied by undetectable levels of the corresponding mRNA transcript, as determined by reverse transcription-polymerase chain reaction. The presence of a missense mutation, when combined with a premature termination codon mutation, may explain the milder blistering tendency of the skin in this patient.
