Computed tomography-occult discoligamentous instability following blunt cervical spine trauma.
Article in BMJ case reports, 2021. 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
Plain CT is routinely ordered following blunt trauma of the cervical spine, and performs well in the exclusion of significant bony injuries. MRI is reserved for cases of suspected neural or posterior ligamentous compromise, and when other imaging modalities are contraindicated. There are patients however, with unremarkable radiology, and without suggestive clinical features, who are later found to have significant discoligamentous instability. In this report, we present two such cases. In both instances, worsening neurological symptoms prompted follow-up imaging, that demonstrated interval development of sub-axial cervical spondylolisthesis, requiring surgery and instrumentation. We identify and discuss radiological features that may be associated with occult discoligamentous injury, and highlight them as avenues for future research. These may prove useful in stratifying at-risk patients for further imaging in the acute setting.
