From: Magnetic resonance imaging changes of sacroiliac joints in patients with recent-onset inflammatory back pain: inter-reader reliability and prevalence of abnormalities

Figure 1

Schematic presentation of the number of pathological findings by the two observers. All abnormalities are graded for extensiveness as 0 (absent), 1 (minimal), 2 (moderate) and 3 (extensive) in the right and left sacroiliac (SI) joints in 68 patients. For inflammation in subchondral bone and bone marrow, and for sclerosis, the data are presented for each site of the joint. For the other abnormalities, the grading for the entire joint per observer is presented.
