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
Background: Vertebral column resection (VCR) is a complex procedure for correcting severe spinal deformities. Traditional imaging techniques may not provide adequate information for preoperative planning. Three-dimensional (3D) printed anatomic models offer a tangible representation of patient-specific anatomy, potentially enhancing surgical planning and outcomes. Methods: This descriptive case series included seven pediatric patients, aged 1-17 years, undergoing VCR at a freestanding pediatric hospital with a high-volume spine program between June 2017 and September 2019. Patient-specific 3D models were created from preoperative computed tomography (CT) scans. Surgeons completed questionnaires at three intervals: premodel review (imaging only), postmodel review, and postsurgery. Data collected included the planned surgical approach, fixation strategy, and vertebral labeling accuracy. Results: Surgical plans were altered in six of seven cases following the review of 3D models. Adjustments included changes in fixation strategy in four cases and modification of the vertebral osteotomy plan in one case. Additionally, the use of 3D models improved vertebral labeling consistency among surgeons, enhancing preoperative planning accuracy. Conclusions: The incorporation of 3D printed models into the preoperative planning of VCR procedures for pediatric patients with complex spinal deformities influenced surgical decision-making. The models provided a better understanding of patient-specific anatomy, leading to modifications in surgical plans and improved vertebral labeling accuracy. These findings suggest that 3D modeling is a valuable tool in enhancing the precision and safety of complex spinal surgeries. Key Concepts: (1)Three-dimensional (3D) printed spine models improve surgical planning.(2)The use of 3D models led to changes in surgical plans in the majority of vertebral column resection (VCR) cases, particularly in fixation strategies and osteotomy decisions. Level of Evidence: IV.
