Genetic insights into the association between serum cytokines and frozen shoulder risk: A bidirectional mendelian randomization study.

This study established a causal association between 41 systemic inflammatory factors and FS, indicating that elevated levels of GROa, IP-10 and CCL5 were associated with a higher risk of FS. Further research is warranted to explore the potential of these biomarkers as early predictors and therapeutic targets for FS.
