Article in Hepatology international, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.

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

backgroundAutoimmune hepatitis (AIH) has been considered a relatively rare disease in Asia, including Japan, where there is a high frequency of infection with hepatitis viruses.

methodWe reviewd the ethnic differences of clinical features of autoimmume hepatitis by reported paper.

resultImmunogenetic predisposition, especially differences in human leukocyte antigens (HLAs), has been pointed out as one of the factors for the occurrence of AIH. In other words, HLA-DR3, which is the first disease-susceptibility gene for AIH discovered in UK and the USA, is extremely rare in Asia including Japan. Moreover, HLA-DR4, which is more frequent than HLA-DR3 in Asia, is associated with a favorable response to treatment and improved prognosis. This also explains why diagnosis and treatment of AIH have not drawn as much attention as viral hepatitis. However, as a survey conducted in Japan shows, the number of patients diagnosed with AIH is increasing. However, the number of elderly patients positive for HLA-DR4 is also increasing in UK and the USA.

conclusionIn the era of genome-wide association studies, further progress of studies on AIH, a typical disease model for immunological liver cell damage, is expected.
