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

Junctional epidermolysis bullosa (JEB) is an autosomal recessive disorder characterized by blister formation at the level of the lamina lucida within the cutaneous basement-membrane zone. Classic lethal JEB (Herlitz type [H-JEB]; OMIM 226700) is frequently associated with premature-termination-codon mutations in both alleles of one of the three genes (LAMA3, LAMC2, or LAMB3) encoding the subunit polypeptides (alpha3, beta3, and gamma2) of laminin 5. In this study, we describe a unique patient with H-JEB, who was homozygous for a nonsense mutation, Q243X, in the LAMB3 gene on chromosome 1 and who had normal karyotype 46,XY. The mother was found to be a carrier of the Q243X mutation, whereas the father had two normal LAMB3 alleles. Nonpaternity was excluded by use of 11 microsatellite markers from six different chromosomes. The use of 17 partly or fully informative microsatellite markers spanning the entire chromosome 1 revealed that the patient had both maternal uniparental meroisodisomy of a 35-cM region on 1q containing the maternal LAMB3 mutation and maternal uniparental heterodisomy of other regions of chromosome 1. Thus, the results suggested that reduction to homozygosity of the 1q region containing the maternal LAMB3 mutation caused the H-JEB phenotype. The patient was normally developed at term and did not show overt dysmorphisms or malformations. This is the first description of uniparental disomy of human chromosome 1.
