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.

Abstract

backgroundAdolescent idiopathic scoliosis (AIS) is a complex three-dimensional spinal deformity affecting 2-4% of adolescents. During the peripubertal stage, untreated AIS may progress rapidly and lead to adverse outcomes such as back pain and poor body image. Full-time bracing, such as the underarm brace (UAB), is indicated for skeletally immature patients with a Cobb angle greater than 20°. Nighttime lateral bending braces (LBB) aim to achieve overcorrection by positioning the patient in a supine bending position opposite to the curve convexity. Despite bracing, 20-30% of patients experience progression requiring surgery. In-brace correction (IBC) is a key determinant of bracing effectiveness. To enhance IBC, we propose a Hybrid Bracing Protocol (HyBP) combining daytime UAB and nighttime LBB.

objectiveThe objective of this trial is to determine whether the Hybrid Bracing Protocol achieves greater in-brace correction (IBC) compared with the conventional bracing at 3 months and 18 months after brace initiation. This 18-month study represents the first phase, followed by a second phase assessing curve outcomes at brace completion and 2 years post-bracing.

methodsThis is a prospective, randomised, parallel-group trial comparing the Hybrid Bracing Protocol (HyBP) with conventional bracing for enhancing in-brace correction (IBC). Skeletally immature female patients with adolescent idiopathic scoliosis and a single thoracolumbar or lumbar curve newly prescribed for bracing will be randomly allocated to either the HyBP group or conventional brace group (CB group). DISCUSSION: To our knowledge, this will be the randomised trial to evaluate the potential synergistic effect of combining two different bracing designs within a hybrid protocol. If effective, this approach may improve bracing outcome, reduce curve progression, and decrease the need for surgical intervention.
