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 at the factor VIII gene locus causing Haemophilia A have now been identified in many patients from many ethnic groups. Earlier studies used biased methods which detected repetitive mutations at a few CG dinucleotides. More recently rapid gene scanning methods have uncovered an extreme diversity of mutations. Over 80 different point mutations, 6 insertions, 7 small deletions, and 60 large deletions have been characterised. Repetitive mutation has been proved for at least 16 CpG sites. All nonsense mutations cause severe disease. Most missense mutations appear to cause instability of the protein, but some are associated with production of dysfunctional factor VIII molecules, thereby localising functionally critical regions of the cofactor. Variable phenotype has been observed in association with three of the latter class of genotype. This catalogue of gene lesions in Haemophilia A will be updated annually.
