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
STUDY
designRetrospective study. PURPOSE: To evaluate the efficacy of a surgical protocol utilizing novel anterior-only reduction and fixation techniques for acute, delayed, and old subaxial cervical facet dislocations. OVERVIEW OF LITERATURE: There is no clear consensus on the optimal surgical approach (anterior, posterior, or combined) for cervical facet dislocation.
methodsOver a 10-year period, 87 consecutive patients with subaxial cervical facet dislocations were treated using an anterior-only approach. Patients were classified into three groups: (1) those indicated for urgent surgery; (2) those contraindicated for urgent surgery; and (3) those with old dislocations. Closed reduction was used in patients contraindicated for urgent surgery. Open reduction involved two anterior-only reduction techniques: modified Caspar pin kyphotic paramedian distraction and anterior facetectomy if required. Fixation was performed with anterior vertebral screw plates for C3/4, C4/5, and selected C5/6 cases, or pedicle screw plates for C6/7, C7/ T1, and C5/6 cases with severe vertebral or articular process fractures.
resultsReduction success rates were 67% for closed reduction, 81% for the modified Caspar pin kyphotic paramedian distraction, and 100% for anterior facetectomy. No supplemental posterior surgery was required. At a minimum follow-up of 12 months, all patients achieved satisfactory fusion without implant failure. Neurological improvement of at least one American Spinal Injury Association grade was observed in 29 patients (43.9%), and no neurological deterioration occurred.
conclusionsThe anterior-only protocol, incorporating modified kyphotic paramedian distraction with Caspar pins, anterior facetectomy, and anterior pedicle screw plate fixation, is safe and effective for managing acute, delayed, and old subaxial cervical facet dislocations.
