From: Accuracy and tolerability of self-sampling of capillary blood for analysis of inflammation and autoantibodies in rheumatoid arthritis patients—results from a randomized controlled trial

Fig. 3

Agreement between capillary and venous blood sampling with respect to C-reactive protein and autoantibody results. Dots show the intraclass correlation coefficients, lines the 95% confidence intervals between self-sampling of the capillary blood from the upper arm (red) or via finger pricking (green) and venous blood sampling. Blue bars show the combined results of the upper arm and finger prick sampling. CCP, anti-cyclic citrullinated peptide antibodies; RF, rheumatoid factor immunoglobulin M; CRP, C-reactive protein
