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

Four intragenic polymorphic microsatellite markers, AAAT Alu repeat, IVS27AC28.4, ACI27.2, and IVS38GT53.0, located along a 65 kb DNA region of the NF1 gene, were used to genotype 64 Spanish families with neurofibromatosis type 1 (NF1). Linkage disequilirium between each pair of markers was evaluated. Three of these markers, AAAT Alu repeat, ACI27.2, and IVS38GT53.0, exhibit linkage disequilibrium between each other. Analysis of extended haplotypes provides further evidence of the disequilibrium within this region since only 11 haplotypes account for 52% of the total chromosomes. Because of linkage disequilibrium, the informativeness of marker combinations for genotyping of NF1 families is diminished. There was no difference in the overall distribution of alleles between affected and normal chromosomes. An at risk haplotype was not found, as expected for a disease with at least 50% of cases being sporadic.
