SGUS Score and Hyperglobulinemia for an Age-Stratified Prediction Model of Positive Labial Focus Score in Sjögren's Disease
Objective To develop and validate a non-invasive predictive model for labial focus score (FS) ≥1 in patients suspected of having Sjögren's disease (SJD), by integrating salivary gland ultrasound (SGUS) findings with clinical parameters. Methods A novel semi-quantitative SGUS sco…
