Fig. 3From: Inhomogeneity of immune cell composition in the synovial sublining: linear mixed modelling indicates differences in distribution and spatial decline of CD68+ macrophages in osteoarthritis and rheumatoid arthritisLinear mixed modelling indicates significant differences in decline of CD68 staining within the synovial sublining between OA and RA. RA shows a faster decline with distance from the lining layer from ROI 1 towards ROI 6 compared to OABack to article page
