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
purposeCervical spinal injury (CSI) following blunt trauma to the neck can have devastating consequences. There is a current controversy surrounding how CSIs are excluded in obtunded patients. This study aimed to evaluate the utility of CT in cervical spine clearance in a high-volume trauma center in a developing world setting.
methodsLongitudinal 11-year data (2012-2022) were collected from the Hybrid Electronic Medical Registry (HEMR), based at the Pietermaritzburg Metropolitan Trauma Service, to identify all obtunded patients (GCS < 15) who underwent a cervical CT scan. The accuracy of CT imaging in identifying CSI was evaluated by calculating the diagnostic sensitivity, specificity, negative predictive value, and positive predictive value against the final admission diagnosis.
resultsIn total, 1039 obtunded blunt trauma patients underwent CT of the C-spine. 121 (12%) of these patients had a CSI demonstrated on CT or MRI. Six (5%) required surgery, and 115 (95%) were treated nonoperatively. In total, 113 (93%) of these patients had a positive CT, and 8 (7%) patients had a false-negative CT but went on to have a positive MRI for CSI; none of these patients with an injury identified on MRI required surgery. CT demonstrated a sensitivity and specificity of 93.4% and 96.2%, with a negative predictive value of 99.1% for identifying CSI.
conclusionIn the obtunded trauma patient, CT correctly identifies all patients with a bony fracture of the cervical spine who will require intervention. In a small subset of patients, CT will miss non-bony injuries. MRI may be necessary for further investigation in the context of persisting clinical concern for CSI (e.g., neurological deficit, polytrauma, unstable vital signs (especially hypotension), and intubation). Most of these non-bony injuries do not require surgery.
