In the original version of the above article the References 19 and 20 were incorrect which cannot describe the development of the SPARCC score.

The original text reads, “Inflammation index of sacroiliac and spine, and structure score of sacroiliac joint by MIR according to criteria of Spondyloarthritis Research Consortium of Canada (SPARCC) [18–20].” Therefore, the authors would like to substitute References 19 and 20, and added reference 3. The text will now read as “Inflammation index of sacroiliac and spine, and structure score of sacroiliac joint by MIR according to criteria of Spondyloarthritis Research Consortium of Canada (SPARCC) [18–21].” The correct references are as follows:
