Acquired Hemophilia A in an Elderly Patient Receiving Clopidogrel: Drug-Induced or Age-Associated Autoimmunity?
Article in Cureus, 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 haemophilia A (AHA) is a rare but potentially life-threatening autoimmune bleeding disorder caused by autoantibodies against factor VIII. Its presentation is often non-specific and can mimic more common causes of bleeding, leading to delayed diagnosis, particularly in elderly patients. We report the case of a 93-year-old man with multiple comorbidities who presented with spontaneous, extensive bruising and haemorrhagic complications. Laboratory evaluation demonstrated findings consistent with AHA, including isolated prolongation of the activated partial thromboplastin time (aPTT), reduced factor VIII activity, and the presence of factor VIII inhibitors. The patient received haematology-directed treatment; however, his clinical course was complicated, and he ultimately died. This case highlights the importance of maintaining a high index of suspicion for AHA in elderly patients presenting with unexplained bleeding and emphasises the need for prompt diagnosis and early multidisciplinary management.
