Chronic thigh hematoma presenting as a suspected soft tissue sarcoma: A case report.
Article in Radiology 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
Chronic expanding hematoma is an uncommon condition that may present as a slowly enlarging soft-tissue mass and closely resemble malignant tumors on imaging. We report the case of a 55-year-old woman with no history of trauma or underlying medical disease who presented with a progressive mass of the left thigh. Imaging studies demonstrated a heterogeneous soft-tissue lesion raising suspicion for a soft-tissue sarcoma. As imaging findings were inconclusive, the patient underwent surgical excision for diagnostic confirmation. Histopathological analysis revealed a chronic expanding hematoma with no evidence of malignancy. This case emphasizes the importance of considering chronic expanding hematoma in the differential diagnosis of slowly growing extremity masses, even in the absence of predisposing factors, to avoid misdiagnosis and inappropriate management.
