Circumferential Thoracic Cord Compression Due to Combined Ossified Yellow Ligament and Ossified Posterior Longitudinal Ligament Managed by a Posterior-Only Approach.
Article in Cureus, 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
Thoracic myelopathy caused by combined ossified yellow ligament (OYL) and ossified posterior longitudinal ligament (OPLL) is exceptionally rare and presents unique diagnostic and surgical challenges. We report a 45-year-old female with rapidly progressive gait disturbance and severe myelopathy found to have circumferential spinal cord compression at T3-T4 due to simultaneous dorsal OYL and ventral OPLL. MRI and CT imaging were essential in defining the extent of compression and ossification. Considering the morbidity of anterior thoracic exposure, a tailored posterior-only approach incorporating laminectomy, OYL excision, costotransversectomy-assisted partial OPLL decompression, and instrumented stabilization was performed, achieving adequate circumferential release. The patient demonstrated meaningful neurological recovery, improving from Nurick Grade 5 to Grade 3 within three months. This case highlights the importance of early recognition, comprehensive imaging, and individualized posterior-based strategies in managing complex upper thoracic stenosis caused by dual ossified pathologies.
