Among the 10 items of the 2022 ACR\/EULAR criteria, the item contributing the most to the reclassification was elevated acute-phase reactant levels (100%), followed by new temporal headache (77.8%) and fluorodeoxyglucose positron emission tomography activity throughout the aorta (77.5%).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>In this study, for the first time, we demonstrated a concordance rate of 100% between the two criteria in Korean patients previously diagnosed with GCA.
