The number of examined joints is higher than in the other tables because ultrasonography and clinical examination were performed on all finger joints, whereas MRI data were not available in 47 joints. All study participants included. Ultrasonography detecting signs of synovitis and/or joint effusion. Clinical joint assessment detecting swelling and/or tenderness. MCP, metacarpophalangeal; PIP, proximal interphalangeal; US, ultrasonography.
