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

The major genetic susceptibility to coeliac disease is contributed by the human leukocyte antigen (HLA) region. The primary association is with the HLA-DQ2 molecule, encoded by the DQA1*05 and DQB1*02 alleles, which is expressed by over 90% of patients. The aim of our study was to perform an extensive scan of the entire HLA region to determine whether there is evidence for the presence of additional HLA susceptibility genes for coeliac disease in the Dutch population, acting independently of DQ2. In all, 16 microsatellite markers and the DQA1 and DQB1 genes were genotyped in simplex cis DQ2-positive coeliac disease families and cis DQ2-positive control families. Allele frequencies of markers on phase-known DQ2-positive haplotypes transmitted to patients were compared to a combined group of DQ2-positive nontransmitted and control haplotypes, thereby controlling for the DQ2 contribution. No significant differences at any of the marker loci were detected, suggesting that DQ2 is the major HLA risk factor for coeliac disease. Individuals homozygous for DQ2 or heterozygous for DQA1*05-DQB1*02/DQA1*0201-DQB1*02 were found to be at five-fold increased risk for development of coeliac disease (P<10(-8)). This risk seems to be conferred by the presence of a second DQB1*02 allele next to one DQA1*05-DQB1*02 haplotype, independently of the second DQA1 allele.
