PD = Power Doppler; JSN = Joint
interphalangeal joint; PIP = proximal interphalangeal joint; MCP = metacarpal joint; CMC1 = first carpometacarpal joint; ICC = intraclass correlation coefficient
a no kappa or ICC value was calculated; reliability was reported as: “interobserver variation 5% (Not Significant)”
b count for total number of osteophytes
c overall kappa over all findings was reported as: “erosions and other findings”
d Reported is the median score of three readers
