Additional file 1: Figure S1. of MMP-3 as a predictor for structural remission in RA patients treated with MTX monotherapy

Receiver operating characteristic (ROC) curve analysis showing that serum matrix metalloproteinase-3 (MMP-3) levels measured at the outset of methotrexate (MTX) monotherapy can predict radiographic evidence of non-progression in male (a) and female (b) patients, respectively.
