Association of thoracic kyphosis angle with shoulder pain, range of motion, isokinetic muscle strength, and upper extremity function.
Article in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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
backgroundThe relationship between kyphosis, and shoulder pain is unclear, and the effects of kyphosis angle on pain severity, range of motion, isokinetic strength, and upper extremity functionality remain undetermined. This study aimed to investigate the correlation between increased thoracic kyphosis and these factors.
methodsThirty participants with a thoracic hyperkyphosis (a mean thoracic kyphosis angle of 57.47 ± 9.96°) were included in the study. The thoracic kyphosis angle was measured using a manual inclinometer. Shoulder pain severity was assessed with the Visual Analog Scale (VAS), shoulder range of motion was evaluated using a manual goniometer, shoulder isokinetic muscle strength was measured with an isokinetic dynamometer, and upper extremity functionality was assessed using the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire.
resultsSignificant correlations were observed between thoracic kyphosis angle and both VAS scores and QuickDASH scores. In addition, the thoracic kyphosis angle was negatively correlated with shoulder flexion, abduction, and external rotation range of motion, as well as internal rotation peak torque. No significant correlations were found between thoracic kyphosis angle and the remaining isokinetic muscle strength parameters.
conclusionsGreater thoracic kyphosis angles were associated with increased shoulder pain severity and reduced shoulder flexion, abduction, and external rotation range of motion, decreased internal rotation peak torque, and impaired upper extremity functionality. These findings suggest that interventions aimed at reducing thoracic kyphosis may contribute to improvements in shoulder pain severity and upper extremity function, potentially through enhancements in joint range of motion and isokinetic muscle strength.
