Comparison and combination of diagnostic performance of CA metabolites in distinguishing SLE active and inactive patients. (Left) ROC curves for commonly used clinical indicators (ESR, C3, C4, and their combination) in identifying active SLE. (Middle) ROC curves for combinations of plasma CA metabolites in distinguishing active and inactive SLE. (Right) ROC curves for combinations of clinical indicators and CA metabolites in stratifying SLE activity.
