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

purposeThe etiology of autoimmune hepatitis (AIH) likely involves a complex interaction of genetic and environmental factors. We aim to investigate the associations between exposure to putative environmental factors and AIH and to quantify AIH risk in a first-degree relative.

methodsWe conducted a population-based case-control study. Cases were AIH patients who were alive and resided in Canterbury, New Zealand, between 1 July 2011 and 30 June 2012. Controls were randomly selected from the Electoral Roll and were matched 2:1 to each case by age and gender. Self-reporting questionnaires that cover lifestyle factors, childhood factors and family history were used.

results72 AIH cases and 144 controls were included. We found that exposure to antibiotics within 12 months prior to AIH diagnosis (OR 12.98, 95 % CI 2.49-67.67, p < 0.01) was an independent risk factor for the development of AIH. Alcohol consumption (OR 0.43, 95 % CI 0.28-0.68, p < 0.01) and childhood home with wood heating (OR 0.30, 95 % CI 0.14-0.63, p < 0.01) were independently associated with reduced risks of later development of AIH. The crude risk of AIH in first-degree relatives of a patient with AIH was 0.2 % (95 % CI <0.1-2.0).

conclusionsWe found that antibiotics are an independent risk factor for the development of AIH, whereas alcohol consumption and living in a childhood home with wood heating are independent protective factors against the later development of AIH.
