Biologics and Drug-Induced Immunogenicity: A Case Report of Acquired Hemophilia A Presenting After Immunotherapy.
Article in Clinical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Acquired hemophilia A is a rare, potentially life-threatening bleeding disorder caused by autoantibody inhibitors to coagulation factor VIII. We report the case of an 87-year-old female who presented with symptomatic bleeding and was subsequently diagnosed with acquired hemophilia A. Her clinical course, treatment, and recovery are described. Notably, her recent medication history included ixekizumab, an immunotherapy agent used for an underlying autoimmune condition, and a course of antibiotics, complicating the identification of a definitive etiology. This case raises the possibility of ixekizumab as a potential novel pharmacologic trigger for AHA. We highlight challenges in establishing causality and review current literature on hematologic manifestations of drug-induced autoimmunity, with a focus on biologic immunotherapies.
