Fig. 2From: Osteoprotegerin and tumor necrosis factor-related apoptosis-inducing ligand as prognostic factors in rheumatoid arthritis: results from the ESPOIR cohortReceiver operating characteristic (ROC) curve to determine the best threshold for OPG/TRAIL ratio to predict rapid erosions. Patients treated with biological therapy during the first 2 years and with radiographic evidence of damage at baseline were excluded.
