  • The frequencies at physical examination represent the frequencies of patients with at least one swollen or tender MCP, wrist or MTP joint.

  • The frequencies at MRI represent the frequencies of all MCP, wrist or MTP joints that had a synovitis, tenosynovitis or BME score of at least 1.

  • For technical reasons some joints on MRI could not be evaluated. Of all 716 MCP joints; 8 synovitis, 17 tenosynovitis and 14 BME scores were not assessed. Of all 179 wrists; 1 synovitis, 2 tenosynovitis and 6 BME scores were not assessed. Of all 895 MTP joints; 29 synovitis and 45 BME scores were not assessed.
