Paraspinal Intramuscular Hemangioma at L5-S1 With Concurrent Disc Herniation.
Article in Journal of medical cases, 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
Intramuscular hemangiomas are rare, benign vascular tumors, with very few reported cases arising in lumbar paraspinal muscles. We describe the seventh documented adult case involving a 39-year-old male presenting with acute severe right-sided S1 radiculopathy. Magnetic resonance imaging (MRI) identified an 8.0 × 3.0 × 3.3 cm lesion within the erector spinae muscles at the L5-S1 level, accompanied by concurrent right-sided L5-S1 disc herniation compressing the S1 nerve root. Conservative treatment initially alleviated radicular pain, but persistent back pain and diagnostic uncertainty necessitated further evaluation. Negative metastatic screening and an inconclusive computed tomography (CT)-guided biopsy led to surgical excision, revealing an intramuscular hemangioma with significant adipocytic stromal components. This case highlights diagnostic challenges and underscores the importance of including vascular lesions in the differential diagnosis of persistent back pain, particularly when coexisting spinal pathologies complicate clinical presentation.
