Paraneoplastic Hyperfibrinolysis in Oesophageal Adenocarcinoma: A Case Report.
Article in Cureus, 2025. 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
Hyperfibrinolysis is a rare but life-threatening coagulopathy that can occur as a paraneoplastic syndrome. It often remains undetected with routine coagulation tests, requiring specialised diagnostics. We present a male patient in his 70s with a history of oesophagectomy for oesophagogastric junction adenocarcinoma who presented with dysphagia, epigastric pain, and spontaneous bruising. Laboratory tests revealed elevated D-dimer, low fibrinogen, and a prolonged prothrombin time. Rotational thromboelastometry (ROTEM) revealed a lysis index at 60 minutes of 53%, consistent with hyperfibrinolysis. Extensive investigations, including imaging and bone marrow biopsy, did not show haematologic malignancy or radiological metastatic disease. A transjugular liver biopsy ultimately confirmed occult metastatic oesophageal adenocarcinoma. This case represents a rare occurrence of primary hyperfibrinolysis linked to oesophageal adenocarcinoma. While the exact pathophysiology remains unclear, it is believed to result from tumour-driven overexpression of fibrinolytic proteins. Given its association with high mortality and poor prognosis, early recognition and intervention are crucial. Standard coagulation tests may fail to detect hyperfibrinolysis, making viscoelastic testing a valuable diagnostic tool. Clinicians should maintain a high index of suspicion for occult malignancy in patients presenting with unexplained bleeding.
