  1. Univariate analyses and interaction with incident (i) or prevalent (p) rheumatoid arthritis (RA). Predicted variable is current health assessment questionnaire (HAQ) score, univariate predictors are current disease activity score in 28 joints using C-reactive protein (DAS28-CRP), sum-scores (SS) for greyscale (GS) and power Doppler (PD) synovitis, GS and PD tenosynovitis (ten), and erosions score (ES). * P value of significance of given β. ** P value of significance of difference between incident and prevalent RA. P-values higlighted in italics are significant at p < 0.05
