Fig. 2From: Validation in the ESPOIR cohort of vitamin K-dependent protein S (PROS) as a potential biomarker capable of predicting response to the methotrexate/etanercept combinationProtein levels for the different classes of patients. Serum PROS (a) or CO7 (b) concentrations in responders (n=24 for ETA/MTX and n=27 for ADA/MTX) and non-responders (n=8 for ETA/MTX and n=5 for ADA/MTX) prior to methotrexate/etanercept or methotrexate/adalimumab initiation in RA patients who have failed to methotrexate in the ESPOIR cohortBack to article page
