Clinical Phenotype, Treatment Exposure, Treat-to-Target Status, and Longitudinal Outcomes in Juvenile-Onset Systemic Lupus Erythematosus: A Single-Center Retrospective Cohort Study

We primarily evaluated last-visit childhood lupus low disease activity state (cLLDAS) status and its limiting components, and secondarily described clinical phenotype, treatment exposure, and outcomes.
