The independent additive value of total greyscale + power Doppler synovitis ... The independent additive value of total greyscale + power Doppler synovitis load (A, B) or scan impression (C, D) is shown among the entire cohort (n = 831; A, C) and the sub-cohort of ACPA-seronegative individuals (n = 703; B, D). AUROCs (95% confidence intervals) for corresponding curves are colour-coded, and P-values denote significant differences between AUROCs (see Methods). See text for further details. AUROC: area under receiver operating characteristic curve; ROC: receiver operating characteristic.
