Identifying Antinuclear Antibody Positive Individuals at Risk for Systemic Autoimmune Disease: Development and Validation of a Real-Time Risk Model
Background/Purpose: Up to 20% of the general population has a positive ANA without having autoimmune disease. Currently, no tools exist to help clinicians interpret the…Abstract Number: 0132 • ACR Convergence 2023
Feasibility of a Real-Time Risk Model to Identify Antinuclear Antibody Positive Individuals at Risk for Systemic Autoimmune Disease
Background/Purpose: Positive antinuclear antibodies (ANAs) cause diagnostic dilemmas for clinicians across multiple specialties. We previously developed and validated a risk model using a de-identified electronic…Abstract Number: 0550 • ACR Convergence 2023
Harnessing Machine Learning to Predict Neuropsychiatric Events in Systemic Lupus Erythematosus
Background/Purpose: Neuropsychiatric systemic lupus erythematosus (NPSLE) is linked to increased morbidity, mortality, and adverse health-related quality of life. Early disease, a history of NPSLE, aPL…Abstract Number: 0971 • ACR Convergence 2023
