Posterior Decompression and Arthrodesis in Congenital Atlantoaxial Subluxation and Associated Complex Vertebral Artery Anomaly: A Case Report.
Article in Journal of orthopaedic case reports, 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
Introduction: The overall incidence of vertebral artery (VA) variations is 2-3%, but among patients with congenital anomalies at the cranio-vertebral junction, it is 20%. Knowing these anomalies is important, if failed to recognize can lead to VA injury during surgery and subsequent cerebrovascular accidents. Case Report: A 14-year-old boy presenting with progressive weakness of bilateral upper limb and lower limb was diagnosed as case of supra-axial cervical myelopathy due to congenital atlantoaxial subluxation with fenestration of VA and high-riding VA. The patient underwent posterior decompression and fusion using C1 lateral mass and C2 laminar screw rod construct. Conclusion: A thorough evaluation of the anatomy of the craniovertebral joint is required in congenital pathologies, and a patient-specific treatment approach should be used. Surgical management can effectively alleviate symptoms and prevent complications, but careful consideration must be given to the risks and benefits of different surgical techniques.
