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

Background: Type II odontoid fracture with backward displacement and ptosis secondary to posterior atlantoaxial dislocation (AAD) due to hyperextension injuries are extremely rare. Case Description: A 72-year-old male with a history of cervical spondylotic myelopathy (CSM) presented quadriparetic after a fall. The cervical magnetic resonance imaging revealed CSM plus posterior AAD associated with marked backward displacement of an odontoid type II fracture. After reduction of the odontoid process, C1 to T2 screw-hook-rod fixation and a subaxial cervical laminectomy/multilevel fusion resulted in marked neurological recovery. Conclusion: Here, a 72-year-old male with underlying CSM presented with the acute onset of quadriparesis following a fall. Having sustained backward displacement/ptosis secondary to posterior AAD from the hyperextension injury, the patient successfully underwent a combined closed/open reduction of the displacement combined with subaxial decompression and long segment fixation.
