Warfarin-associated Spontaneous Hemorrhage from the Lateral Pectoral Artery after Reverse Total Shoulder Arthroplasty: A Case Report.
Article in Journal of orthopaedic 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
Introduction: Warfarin is a widely used anticoagulant with a narrow therapeutic index and significant bleeding risk. Accounts of warfarin-associated spontaneous hemorrhage have been documented, but few reports in the orthopedic literature describe this event and its complications following reinitiation of warfarin in the post-operative period. Case Report: A 70-year-old Caucasian woman with antiphospholipid syndrome developed spontaneous hemorrhage from the lateral pectoral artery following reinitiation of warfarin after ipsilateral reverse total shoulder arthroplasty (RTSA), successfully managed with anticoagulation reversal, embolization, and chest wall hematoma evacuation. To our knowledge, this is the first case report of perioperative warfarin-associated spontaneous hemorrhage from the lateral pectoral artery after RTSA. Conclusion: As surgical candidates become more medically complex, it is essential that surgeons develop the ability to identify preoperatively patients at high risk for bleeding, take steps to minimize risk factors for bleeding, and learn how to manage spontaneous hemorrhage using a multidisciplinary approach.
