  1. Data presented as mean (95% confidence interval). Inter-observer reliability of total and segmental FAt Spondyloarthritis Spine Score as assessed by two readers in Exercise 1 (n = 58) and Exercise 2 (n = 135), and the 77 new patients included in Exercise 2. The 58 patients from Exercise 1 were nested randomly within the new 77 patients included in Exercise 2.
