Brace yourself (Part-time): part-time bracing leads to curve improvement in juvenile idiopathic scoliosis.
Article in Spine deformity, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThe efficacy of bracing for juvenile idiopathic scoliosis (JIS) remains controversial. Although full-time bracing is standard for curves > 25°, part-time bracing for smaller curves (< 25°) may prevent progression. This study evaluates the effectiveness of part-time bracing compared to observation in JIS patients with 15-24° curves, hypothesizing that part-time bracing reduces curve progression and the need for full-time bracing.
methodsThis retrospective cohort study reviewed skeletally immature JIS patients (4-10 years old) with 15-24° curves. Patients underwent either observation or part-time bracing (8-12 h/day). Minimum two-year outcomes included: (1) curve change (> 5°), (2) progression to > 25° requiring full-time bracing, and (3) prescription for full-time bracing.
resultsEighty-three patients (59% observed, 41% braced) were analyzed. The braced cohort demonstrated slightly higher baseline curves (+ 1.6°, p = 0.01). By final follow-up, braced patients improved by 3.2° (p = 0.05), while the observed cohort worsened by 3.4° (p = 0.05). More braced patients improved > 5° (69% vs. 21%, p < 0.001), whereas more observed patients progressed > 5° (54% vs. 11%, p < 0.001) and to > 25° (54% vs. 20%, p = 0.002). Full-time bracing was prescribed for 63% of observed patients but only 17% of braced patients (p < 0.001).
conclusionPart-time bracing not only prevents curve progression, but also frequently leads to improved curve magnitude in JIS patients with smaller curves, minimizing the need for full-time bracing.
