Table 3.

Interreader reliability (intraclass correlation coefficients, ICC) per reader pair (Exercise 2). Key to ICC values: Very good, ICC ≥ 0.80; good: 0.50 ≤ ICC < 0.80; poor: 0.20 ≤ ICC < 0.50; trivial: ICC < 0.20; values are average measure ICC. Readers 1 to 4 have rheumatological background, while Reader 5 is a musculoskeletal radiologist. Median interreader ICC 0.83.
