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
purposeTo describe the technique of percutaneous image-guided anterior screw fixation of the odontoid process in five patients using hydrodissection of the jugulo-carotid and pre-vertebral spaces. METHODS AND MATERIALS: Between 03/2018 and 03/2020, five patients from two university hospitals underwent a percutaneous image-guided anterior screw fixation of the odontoid process for one pathological fracture, two impending fractures and two traumatic fractures of the dens. Technical success was defined as a satisfactory positioning of the screw in the odontoid. Detailed data with the number and type of needles required, the time to perform hydrodissection, the volume of fluid used, the time for bone access, the size and lengths of the screws used, technical success, complications, clinical outcomes and follow-up were retrospectively assessed.
resultsTechnical success was achieved in 100% (5/5 cases), with a mean volume of hydrodissection of 218 ± 8.4 mL (range 210-230). Mean total procedure time was 112 ± 34 min (range 70-160). The lengths of the screws ranged from 30 mm to 55 mm. Additional cementoplasty was performed in the three malignant cases. VAS scores dropped on a 10-point scale from mean 5.8 ± 2.2 pre-procedure to 0.8 ± 0.4 after the procedure. No major complication occurred.
conclusionPercutaneous image-guided anterior screw fixation of the odontoid process using hydrodissection of the jugulo-carotid and pre-vertebral spaces is technically feasible and seems safe.
