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.
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
Many studies have shown an association of IDDM with polymorphisms in the HLA region on chromosome 6p21. Previously our case-control study in the Belgian population showed significant association between IDDM and certain HLA class II alleles, in particular Lys71+, encoding DRB1 alleles. In the present study, 81 Danish multiplex IDDM families and 82 healthy Danish controls were examined for polymorphisms in the HLA-DRB genes and 54 of the 81 families for polymorphisms in HLA-B, -DQA1, -DQB1, -TNFA, and -TNFB genes. The results confirm our previous studies in the Belgian population and show that DRB1Lya71+/+ homozygotes have a relative risk (RR) of 103.5. Linkage between IDDM and DRB1 alleles that encode Lys71+ was shown by affected zib pair analysis which showed strong linkage (p < 1 x 10(-6). By family based association studies, the DRB1Lys71+ was identified as the allale which increased susceptibility to develop IDDM most in the HLA region (haplotype relative risk = 8.38). Haplotype analysis confirmed the increased risk contributed by DRB1Lys71+ alleles and in addition showed that DRB1Lys71- provides protection against IDDM even in the presence of DQB1Aep47-. These results indicate that DRB1Lys71+ screening is a powerful test compared to full HLA typing to determine the risk for a random person to develop IDDM in the Danish population, with an even higher probability than shown previously for the Belgians.
