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
Objective: This study aims to investigate the efficacy of a simple and effective two-dimensional integrated navigation-guided spinal endoscopic interbody fusion surgery for the treatment of lumbar spondylolisthesis. Methods: A retrospective analysis was conducted on the clinical data of patients with lumbar spondylolisthesis treated with or without navigation. Postoperative clinical data were collected, and pain levels were assessed using the Visual Analog Scale (VAS), while functional improvement was evaluated using the Oswestry Disability Index (ODI). At the final follow-up, x-ray imaging was used to measure disc height (DH), slip percentage (SP), lumbar lordosis (LL), and slip angle (SA) at the surgical segment. Interbody fusion status was assessed based on the Bridwell grading criteria. Results: ULIF surgery for lumbar spondylolisthesis with navigation assistance yields favorable early outcomes, including reduced surgery duration, fewer fluoroscopy instances, lower intraoperative blood loss, and less postoperative drainage volume ( Conclusion: Compared with the non-navigation group, the ULIF procedure guided by the two-dimensional integrated navigation system-which is simple and effective-can provide better early relief of low back pain in patients with lumbar spondylolisthesis, while also shortening operative time, reducing the number of fluoroscopy instances, minimizing intraoperative blood loss, and decreasing postoperative drainage volume. This surgical approach demonstrates great potential for widespread clinical application.
