Receiver operating characteristic curve analysis of baseline expression of miR-125b in peripheral blood mononuclear cells as a predictor of achieving optimal treatment outcome (28-joint count disease activity score (DAS28 < 3.2) after 3 months. Baseline miR-125b expression (solid black line) had the highest area under the curve (0.663 (0.520–0.805); p = 0.048). C-reactive protein (CRP) (dashed-dotted black line), erythrocyte sedimentation rate (ESR) (dashed black line) and DAS28 (dotted black line) at baseline are presented
