1 · What the graph read from it

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.

2 · The registry

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

backgroundThoracic scoliosis causes complex three-dimensional deformities of the thoracic cage that can impair lung mechanics and airway geometry, leading to restrictive ventilatory dysfunction. Respiratory impairment differs by etiology, with non-idiopathic scoliosis often showing more severe and persistent deformity. Conventional pulmonary function testing provides global functional assessment but is frequently limited in patients with non-idiopathic scoliosis. Advances in chest computed tomography (CT) allow quantitative evaluation of lung volume and airway morphology, offering an alternative approach to assess respiratory function and the relationship to spinal deformity.

aimTo investigate CT-derived airway morphology and respiratory function in thoracic scoliosis, focusing on etiologic differences and structure-function relationships.

methodsThis retrospective observational study included 53 patients ≤ 30 years of age who underwent corrective surgery for thoracic scoliosis and had preoperative and postoperative CT examinations. Patients were classified into idiopathic (

resultsPatients with non-idiopathic scoliosis had significantly more severe spinal deformities and a lower TLC% compared to patients with idiopathic scoliosis (median TLC%: 39%

conclusionCT-derived analysis showed differences in respiratory impairment between idiopathic and non-idiopathic scoliosis. Surgical correction improved alignment without immediate lung volume improvement, with selective changes in the left bronchus.
