An accurate predictive model for depressive symptoms in patients with primary Sjögren's disease based on machine learning algorithms

Clin Exp RheumatolPublished Retrospective cohort study

Authors' conclusion

This study presents the first ML-based model for predicting depressive symptoms in pSjD patients, highlighting the significance of immuno-inflammatory and clinical factors in depression pathogenesis.
