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
backgroundLateral mass screw and rod fixation is widely used for posterior cervical arthrodesis and stabilization in cases of cervical instability, trauma, neoplasm, decompression, and deformity correction. However, clinical and radiological data on its outcomes, especially in our setting, remain limited.
objectiveClinical and radiographic evaluation of posterior cervical arthrodesis and stabilization using lateral mass screws and rod fixation.
methodsA retrospective cross-sectional study of lateral mass screw and rod fixation from September 2019 to September 2024 was performed, and the clinical and radiographic parameters were evaluated. Sixty-six patients were assessed via a structured questionnaire. Clinical parameters were assessed by the ASIA score, functional assessment in degenerative conditions (mJOA), and radiographic evaluation (computed tomography and dynamic X-ray) of 325 lateral mass screws inserted into the evaluated patients. Complications were assessed from a patient chart and radiology archive.
resultsPatients ranged from 16 to 75 years in age (40.1), and 84.9% of the patients were between the ages of 20 and 60. Trauma accounted for 92.4% of the indications, with fracture dislocations being C4/C5 (28.8%), C5/C6 (25.8%), C6/C7 (16%), and C4/5 (10.8%)-unilateral locked facets in 4.5% and floating lateral masses in 6% of patients. A total of 325 screws were placed, with C5 being the most common (110 screws). There was no postoperative change in the ASIA score. The complications included dural tear (3%), joint violation (1.9%), hardware failure (1 patient), and postoperative surgical site infection (6%). The postoperative follow-up ASIA score was significantly associated with the preoperative score, with a likelihood ratio and Fisher's exact test P value < 0.001. The mean postoperative follow-up mJOA score was 13.3 ± 0.58, which was greater than the preoperative mean mJOA score, which was 8.67 ± 1.16.
conclusionLateral mass screw and rod fixation is an effective method of cervical stabilization in our setting. CLINICAL TRIAL NUMBER: Not applicable.
