Serum Cyr61 concentrations and diagnostic performance of Cyr61 in participants in the training cohort. a Levels of serum Cyr61 in healthy controls and RA patients (classified into inactive RA group and active RA group as evaluated by DAS28-ESR ≥ 3.2). b Receiver operating characteristic (ROC) curve to determine the best threshold for Cyr61 to discriminate RA and healthy controls. The red horizontal solid line represents a median value
