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
Objectives: The aim of this study was to investigate the safety and feasibility of 3D-printed puncture guides assisting in unilateral-approach percutaneous vertebroplasty (PVP) for the treatment of osteoporotic vertebral compression fractures (OVCFs). Methods: We retrospectively analyzed the medical records of 106 patients admitted to the Department of Spine Surgery of the Affiliated Hospital of Yan'an University who underwent PVP with a unilateral approach from June 2020 to June 2022, and divided them into 2 groups based on the use of 3D-printed perforation guides during the operation: 52 patients in the 3D-printed perforation guide-assisted PVP group (Observation group), and 54 patients in the traditional PVP group (Control group). The general information, operation time, puncture time, number of intraoperative C-arm fluoroscopies, amount of bone cement injected, postoperative complications, pedicle wall breaches by the puncture needle trajectory, and the degree of compression of the anterior margin of the vertebral body and the Cobb's angle, which were measured on the lateral views of the injured vertebrae preoperatively and postoperatively, were recorded and compared between the two groups. A visual analogue scale (VAS) was used to evaluate the degree of pain in the injured vertebral region, and the Oswestry Disability Index (ODI) was used to assess the degree of functional disability of the patients. Results: (1) There were no statistically significant differences between the two groups regarding gender, age, body mass index (BMI), bone mineral density (BMD), injured segment, and other baseline characteristics ( Conclusion: 3D-printed puncture guide-assisted unilateral approach PVP for the treatment of single-segment OVCFs has significant clinical advantages compared with the traditional unarmed puncture group. Specifically, it improves the ratio of overall to contralateral bone cement dispersion volume, significantly enhances puncture accuracy, and reduces the incidence of surgical complications. It also reduces the number of fluoroscopies, shortens the operative time, and comprehensively improves surgical safety and operational efficiency.
