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
backgroundAdolescent idiopathic scoliosis (AIS) can be associated with restrictive lung disease. Brace wearing is also associated with restrictive lung disease. Due to external compression, bracing could alter the biomechanical function of the rib cage. The aim of this work was to test the feasibility of using biplanar radiography to study the impact of the brace on the rib cage kinematics during breathing. MATERIALS AND
methodsTwelve patients with moderate AIS, treated with Cheneau-Toulouse-Munster (CTM) brace, underwent pulmonary function test and biplanar radiography at two lung volumes: normal breathing and full inspiration with and without brace. Their spine and rib cage were reconstructed in 3D from the radiographs.
resultsLung volumes were reduced after application of the brace, both by pulmonary function test and 3D reconstruction. The reduction in the rib cage volume appeared to be due to changes in rib cage width, in relation to the pressure pads. Costo-vertebral strategy did not seem to be modified by brace wearing. The brace tended to increase the correction of the cobb angle in maximum inspiration.
conclusionsThis study confirms the relevance of assessing respiratory function using biplanar radiography and 3D reconstruction. By reducing lung volumes without changing the costo-vertebral strategy, the impact of the Cheneau brace on ventilation remains to be clarified. LEVEL OF EVIDENCE: III, prospective.
