Azathioprine hypersensitivity syndrome: report of two cases.
Article in BMJ case reports, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Azathioprine hypersensitivity syndrome is a rare but potentially severe side effect of azathioprine use. It has a variable and non-specific presentation making it difficult to distinguish from sepsis or disease relapse. High clinical suspicion is therefore required for recognition and prompt cessation of azathioprine for symptom resolution. Herewith two cases of severe azathioprine hypersensitivity syndrome are described, one in association with Sweet syndrome. Both presented with vague symptoms 2 weeks after commencing azathioprine for antineutrophil cytoplasmic antibody vasculitis. The differentials of sepsis and disease relapse were considered prior to cessation of azathioprine which resulted in a dramatic improvement in both cases. These cases highlight the diagnostic challenge azathioprine hypersensitivity syndrome presents. It should be suspected when there is a temporal relationship to drug initiation, with absence of infection or serological evidence of disease relapse.
