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 and importance: Thoracic ossification of the posterior longitudinal ligament (T-OPLL) causes severe neurological deficits. Surgical management is challenging due to the thoracic spine's anatomical complexity. This case report aims to describe a novel hybrid open-endoscopic technique for the treatment of severe thoracic OPLL, with the objective of demonstrating its feasibility and safety in a high-risk obese patient. Presentation of case: A 29-year-old male with class III obesity was hospitalized for progressive bilateral lower extremity weakness over 2 months, recently worsening with new-onset numbness. Examination revealed hypoesthesia below the costal margin, decreased lower extremity motor strength, and reduced anal tone. Imaging showed T-OPLL at T5/6 with significant spinal cord compression and stenosis. Complete 360° decompression was achieved via posterior open laminectomy using an ultrasonic bone scalpel, combined with ventral decompression via minimally invasive endoscopy. The patient had satisfactory outcomes without complications. Clinical discussion: The full endoscopic transforaminal approach has been successfully used in ventral thoracic spinal cord compression. However, due to the narrow spinal canal and small intervertebral foramina in the thoracic region, the limited operational space during cannula placement and removal of ventral ossified lesions still leads to complications. To address this, we first performed a total laminectomy in this case to achieve indirect dorsal decompression, followed by foraminotomy under direct visualization. This preparatory step created sufficient working space for subsequent cannula insertion and ventral decompression, minimizing spinal cord manipulation and effectively reducing iatrogenic spinal cord injury. Conclusion: This study introduces a combined surgical approach. Integrating open and minimally invasive endoscopic techniques achieves comprehensive 360° decompression while minimizing trauma and complications. This hybrid technique is an alternative for severe thoracic spinal stenosis primarily from ventral compression.
