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
objectiveThis study aims to evaluate and compare the clinical and radiographic outcomes of patients with metastatic spinal tumors who underwent either short-segment fixation with anterior support or long-segment fixation with a separation surgery in the thoracic or lumbar spine.
methodsWe conducted a retrospective analysis of adult patients who were treated surgically for spinal metastases in the thoracic or lumbar spine at a single tertiary referral center between April 2014 and December 2022. Surgical treatments included spinal cord decompression, short-segment fixation with maximal circumferential debulking of the lytic tumor portion and anterior support, or longsegment fixation without anterior support, followed by separation surgery and posterolateral fusion. We compared the two fixation strategies based on patient demographics, preoperative diagnoses, surgical data, neurological assessments, and changes in segmental Cobb angles immediately after surgery, and at the final follow-up.
resultsA total of 91 patients were included (short-segment, 44; long-segment, 47). No significant differences were observed between the groups regarding age, sex, comorbidities, primary cancer location, postoperative complications, or reoperation rates. Furthermore, no significant differences in the sagittal Cobb angles, including global angle (thoracic kyphosis, lumbar lordosis) and segmental angle were noted from the preop to the final follow-up. Compared to traditional long-segment fixation, short-segment fixation with anterior support significantly improved neurological outcomes in the thoracic region and reduced the length of hospital stay. No significant differences were observed between the two groups regarding complications or other clinical outcomes.
conclusionShort-segment fixation is comparable to long-segment fixation in the management of thoracolumbar metastatic spinal tumors, with no significant differences in radiographic outcomes. However, short-segment fixation provides the added advantages of improved neurological outcomes in the thoracic region and shorter hospital stays.
