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
backgroundSpontaneous oral extrusion of cervical spine hardware is an exceptionally rare complication following anterior cervical discectomy and fusion (ACDF), with only a few cases documented in the literature, none involving a stand-alone interbody cage. CASE PRESENTATION: This paper presents what appears to be the first reported case of spontaneous expectoration of a stand-alone cervical cage in a 54-year-old man, two years after undergoing ACDF at the C3–C4 level. The patient experienced progressive dysphagia and foreign-body sensation, culminating in sudden expulsion of the implant during a coughing episode. Imaging revealed a large prevertebral collection with a fistulous tract to the hypopharynx, but without bone erosion, acute infection, or neurological deficits. Conservative management with intravenous antibiotics and close clinical monitoring led to a favorable outcome, avoiding surgical intervention.
resultsA systematic review of the literature identified 14 similar cases of oral extrusion of cervical hardware, most involving screws, bone grafts, or constructs, but none describing the expulsion of an unplated interbody cage.
conclusionThis case emphasizes the need for long-term vigilance following ACDF, even in seemingly uncomplicated cases, and suggests that conservative treatment may be an appropriate strategy in select, clinically stable patients.
