ΔAMRICS, change in Auckland MRI cartilage score from baseline (2009) to three years (2012); ΔXR jsn, change in X-Ray joint space narrowing (Sharp van der Heijde score, hands only) from baseline to three years; SD, standard deviation; SE, standard error; SRM, standardised response mean.

*P-value for significance of difference between RA patients and controls.
