Number of intra-articular triamcinolone injections in patients from the CXCL13- high and - low group between baseline and two years. Aligned dot-plot of the number of intra-articular injections is presented as total number of injection between baseline and two years. CXCL13-high DMARD + ADA (n = 27) and DMARD (n = 23), CXCL13-low DMARD + ADA (n = 10) and DMARD (n = 16). Further, the number of intra-articular injections is stratified into number of injections before six months and between six months and 2 years (mean with SD). ADA: adalimumab; CXCR13: C-X-C chemokine receptor type 13; DMARD: disease-modifying anti-rheumatic drug; SD: standard deviation.
