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
Introduction Thoracolumbar fractures, particularly burst fractures, represent a significant health concern due to their prevalence and functional impact. This study evaluates the efficacy of short-segment posterior fixation with intermediate screw instrumentation in treating unstable thoracolumbar fractures. Methods A prospective study was conducted from July 2022 to December 2023, including 26 patients with traumatic thoracolumbar fractures. Surgical intervention was indicated for patients with a thoracolumbar injury classification and severity (TLICS) score >4. Functional outcomes were assessed using the visual analog scale (VAS), Oswestry Disability Index (ODI), and the American Spinal Injury Association (ASIA) grading system. Radiological outcomes, including the local kyphotic angle (LKA) and anterior vertebral body height ratio (AVBHR), were evaluated preoperatively, postoperatively, and at follow-ups. Results Significant improvements in functional and radiological parameters were observed over 24 weeks. The mean VAS score reduced from 7.50 ± 0.58 preoperatively to 1.42 ± 0.50 (p < 0.001), and the mean ODI improved from 42.23 ± 3.54 to 16.12 ± 3.09 (p < 0.001). Neurological improvements were seen in ASIA grades B-D, with no new deficits. Radiologically, the mean LKA improved from 19.73 ± 1.59° preoperatively to 8.46 ± 1.33° at 24 weeks (p < 0.001), and the AVBHR increased from 34.08 ± 2.25% to 86.64 ± 0.83% (p < 0.001). No implant failures were reported. Conclusion Short-segment fixation with intermediate screws provides effective stabilization and significant functional and radiological improvements in thoracolumbar fractures. It minimizes intraoperative morbidity and preserves motion segments, making it a viable alternative to long-segment fixation, particularly for non-complex fractures. Further randomized controlled trials are recommended to validate these findings.
