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 evaluate the feasibility and preliminary clinical outcomes of percutaneous endoscopic visual trephine decompression (PEVTD) in combination with pedicle screw fixation for the treatment of lumbar burst fractures with secondary spinal stenosis.
methodsA retrospective analysis was conducted on 21 patients with lumbar burst fractures and secondary spinal stenosis treated from December 2022 to December 2024. All patients underwent PEVTD combined with percutaneous pedicle screw internal fixation. The duration of endoscopic decompression surgery, blood loss, the incidence of intraoperative dural tearing, the Visual Analogue Scale (VAS) for pain score, the American Spinal Injury Association (ASIA) grade, and the MRI dural sac cross-sectional area were recorded to assess the effectiveness of decompression.
resultsThe mean operative time for endoscopic decompression was 49.3 ± 10.2 min (41-60 min) with an estimated blood loss of approximately 160 ml. No intraoperative dural tearing occurred. Compared with the preoperative values, the postoperative VAS score and ASIA grade at 1 week and 1 year significantly improved(P < 0.05). The dural sac cross-sectional area increased significantly postoperatively (P < 0.01).
conclusionPEVTD appears to be a feasible minimally invasive technique for treating lumbar burst fractures with secondary spinal canal stenosis in selected patients (those without posterior column injury and with ≤ 50% canal compromise). The preliminary results suggest that PEVTD is a feasible minimally invasive technique with short-term outcomes that appear acceptable in this selected cohort, although these findings are exploratory and require confirmation in prospective comparative studies.
