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 aimed to evaluate the clinical efficacy and safety of the dual growing rods (DGR) technique combined with preoperative halo-femoral traction (HFT) in treating early onset scoliosis (EOS), with a focus on spinal deformity correction, preservation of spinal growth, and complication management. The integral role of preoperative HFT in enabling DGR implantation for severe rigid curves was a primary focus of the analysis.
methodsA retrospective study was conducted on 42 EOS patients treated with the DGR technique, with a mean follow-up of 38.10 ± 12.95 months. Radiographic parameters-including Cobb angle, T1-S1 distance, apical vertebral translation (AVT), and sagittal alignment-were measured preoperatively, postoperatively, and at final follow-up. Complications were recorded and analyzed. Subgroup analysis compared patients with and without preoperative HFT.
resultsAt final follow-up, the main Cobb angle correction rate was 64.30% ± 17.51%, and the T1-S1 distance increased significantly (p < 0.05), indicating preserved spinal growth. The overall complication rate was 19.1% (8/42), including screw loosening or displacement (n = 3), hook disengagement (n = 2), proximal junctional kyphosis (n = 2), and wound-healing issues (n = 2). No significant association was found between complications and age, etiology, or HFT use (p > 0.05). Patients undergoing preoperative HFT showed improved spinal flexibility, enabling successful DGR placement despite severe rigidity.
conclusionThe DGR technique combined with preoperative HFT is a safe and effective treatment for EOS, achieving substantial deformity correction and supporting spinal growth. Preoperative HFT is a necessary adjunct for severe rigid deformities, directly enabling DGR implantation and enhancing correction efficacy.
