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
BACKGROUND Acquired hemophilia A (AHA) is a rare and potentially life-threatening bleeding disorder characterized by the formation of autoantibodies targeting coagulation factor VIII (FVIII). This condition poses considerable diagnostic and therapeutic challenges, requiring a multidisciplinary approach. Despite advancements in treatment, literature on the management of bleeding episodes in patients with hemophilia undergoing endovascular procedures remains limited. It is essential to acknowledge the significance of timely diagnosis and customized intervention for enhancing outcomes. CASE REPORT We report the case of an 82-year-old woman presenting with a large hematoma on the anterior surface of the left thigh due to AHA. The patient was initially treated with immunosuppression combined with administration of recombinant activated FVII, but there was no observed response. The patient's condition worsened, leading to hemodynamic instability. Consequently, CT angiography was performed, which identified extravasation from a branch of the left superficial femoral artery. Following this, the patient underwent successful endovascular embolization of the bleeding vessel, leading to effective hemorrhage control without complications. The whole procedure was performed under hemostasis expert supervision and administration of recombinant activated human FVII. CONCLUSIONS This case highlights that endovascular embolization can be a safe and effective option for controlling bleeding in selected patients, particularly when traditional strategies are insufficient. Its success depends on a multidisciplinary approach and collaboration among various medical specialists under the supervision of hemostasis experts, due to the high periprocedural risks.
