1 · What the graph read from it

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.

2 · The registry

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: Surgeries in the occipitocervical and upper cervical region are always quite challenging and need adequate surgical experience and expertise. Especially in cases, where both anterior and posterior surgical access is required, complication rates could be significantly high. The transoral approach for the ventral pathologies of the upper cervical region has been previously described using the conventional open technique where post-operative morbidity is a concern. Moreover, problems such as dysphagia, risk of injury to the oral components, and surgical site infection are always an issue. In patients requiring a combined posterior approach, surgical morbidity, and post-operative recovery is always an area of concern. We describe a case report of upper cervical myelopathy managed under full navigation using a combined tubular transoral (minimally invasive) and posterior approach. Case Report: A 74-year-old male patient presented with myelopathy and weakness in bilateral upper and lower limbs (MRC Grade 4/5) due to a cystic lesion at C1 causing ventral cord compression. A staged anterior (minimally invasive transoral tubular approach) - posterior procedure was performed under full navigation for decompression and stabilization of C1-C2. Postoperatively, the patient showed neurological improvement (MRC Grade 5/5) in all four limbs. Conclusion: A 360° navigation-guided approach to the upper cervical spine is a safer and more effective procedure with less risk of neurological and vascular complications. Furthermore, combining minimally invasive access anteriorly to the odontoid ensures reduced surgical morbidity of the overall procedure.
