Effect of Vertebral Body Tether Tensioning on Vertebral Body Growth Modulation.
Article in JOR spine, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: The relationship between tether tension and spinal growth modulation following vertebral body tethering (VBT) has not been studied in growing children. Aims: This study aims to explore the relationship between vertebral body growth modulation under varying tether tension. Materials and Methods: A retrospective, multicenter pediatric registry was queried for idiopathic scoliosis patients treated with right-sided VBT, with recorded intraoperative tension (using an ordinal scale of 0-3), and 3D reconstructions from biplanar radiographs at the first erect (FE) and 2-year post-operative visits. Custom MATLAB code was used to calculate vertebral height (mm) on the untethered and tethered sides from T5-T12. Generalized linear mixed models were used to analyze the effect of tension on vertebral body growth. Results: Fifty-two subjects (47 female) were included with a mean age of 12.5 ± 1 years. Patients were skeletally immature (triradiate cartilage open in 23 patients) with Proximal Femoral Maturity Index scores of 2 (nine patients), 3 (21 patients), 4 (20 patients), and 5 (two patients). A total of 330 vertebral bodies were analyzed. Mean height change of the vertebral bodies from FE to 2 years was 1.6 + 1.9 mm (untethered) and 1.2 + 1.8 mm (tethered). On the tethered side, greater tension resulted in less height change, with the greatest differential growth observed between maximal tension and no tension (0.8 mm vs. 0.2 mm, Conclusion: Intraoperative intervertebral tensioning significantly affects vertebral body growth over 2 years.
