Association between incorrect posture and curve types in adolescent idiopathic scoliosis: a large-sample, cross-sectional study in China.
Article in Frontiers in public health, 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
Background: Screening for adolescent idiopathic scoliosis (AIS) has progressed considerably in recent years. However, specific physical indicators for accurately determining spinal curve types are lacking. This study aimed to explore the association between incorrect posture and curve types in AIS. Methods: We analyzed data from 10,453 students who underwent full-spine evaluation in the outpatient department between 2022 and 2023. Assessments included postural observations, Adam's Forward Bending Test, angle of trunk rotation (ATR), and full-spine radiographic imaging. Correlation and logistic regression (LR) models were used to analyze the associations among incorrect posture, curve magnitude, and curve type. Results: Incorrect postures, particularly the presence of a rib hump, were significantly correlated with the curve magnitude in AIS. Univariate LR analysis showed that female, age, Risser sign, and incorrect postures were identified as associated factors for the curve type. Multivariate LR analysis revealed that right scapular tilt [odds ratio (OR): 1.553, 95% confidence interval (CI): 1.192-2.025, Conclusion: Incorrect posture and ATR, especially right rib hump, were significantly associated with curve magnitude and curve type in AIS. These indicators can provide an objective reference for triaging children referred from school-based screening for AIS, facilitating a more targeted and efficient identification of at-risk individuals.
