Follow-up of syringomyelia due to Chiari type I malformation with phase-contrast magnetic resonance imaging in a professional athlete.
Article in Surgical neurology international, 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
Background: Chiari type I malformation (CM-I) is characterized by the descent of the cerebellar tonsils ≥5 mm below the foramen magnum and is frequently associated with syringomyelia (SM). In professional athletes, these conditions may be incidentally discovered following mild trauma. However, the literature offers limited guidance on safe return-to-play criteria. Case Description: A 22-year-old professional rugby player was diagnosed with CM-I and SM. His only symptom was sleep apnea, confirmed by polysomnography. Magnetic resonance imaging (MRI) revealed a 17 mm tonsillar descent and a C3-C4 syrinx. Craniocervical decompression with duraplasty was performed. Five months postoperatively, the phase-contrast MRI (PC-MRI) demonstrated persistent SM with cerebrospinal fluid (CSF) flow velocities of 10 cm/s. By 16 postoperative months, the syrinx had resolved, and CSF velocities normalized. These findings guided the decision to clear the patient to return to professional contact sports. Conclusion: In this case, PC-MRI provided objective postoperative data that determined sufficient recovery from CM-I decompression and allowed the 22-year-old athlete to return to his high-impact sport.
