Quantification of IL-12p40 levels in synovial fluid. Synovial fluid was collected at day 7, 14 and 21 after intra-articular injection of PBS and BSA. Cytokine levels were determined by Luminex xMAP technology. The lower boundary of the box indicates the 25th percentile and the upper boundary the 75th percentile. Bars above and below the box indicate the 90th and 10th percentiles. The line within the box marks the median (n = 4). Dot line indicates the basal levels (just before intra-articular injection). *Statistically significant difference (p ≤ 0.05) compared to basal level
