1 · What the graph read from it

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.

2 · The registry

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

We report a case of idiopathic retroperitoneal hematoma in an 82-year-old man with moderate COVID-19 pneumonia receiving prophylactic anticoagulation therapy. The patient was initially treated with remdesivir, dexamethasone, and subcutaneous heparin, showing improved respiratory function. On hospital day 6, he developed sudden right lower abdominal pain without prior trauma. Physical examination revealed abdominal distension and tenderness. Laboratory tests showed no evidence of coagulopathy. Contrast-enhanced computed tomography identified active bleeding in the right iliopsoas muscle, consistent with retroperitoneal hematoma. The patient was transferred to a tertiary center for management. This case underscores that retroperitoneal hematoma can occur even in moderately ill COVID-19 patients without abnormal coagulation markers. Vigilant physical examination and early imaging are essential for timely diagnosis. Individualized risk assessment is critical when initiating anticoagulation therapy in elderly patients with comorbidities.
