The association between synovial fluid (SF) IL-6 and quantitative findings of ultrasonography in treated patients with rheumatoid arthritis (RA). a SF IL-6 is higher in patients with RA and low synovial echogenicity, regardless of their synovial hypertrophy. b There was no statistically significant difference in SF IL-6 levels between patients with hyperechogenic synovium with high vascularity and hypoechogenic synovium with low vascularity. GS score, quantitative grayscale area; PD score, quantitative power Doppler area. *Significant correlation (p < 0.05)
