The performance of the 2022 ACR/EULAR classification criteria for Takayasu’s arteritis as compared to the 1990 ACR classification criteria in a Chinese population

In this study, we studied the performance of the 2022 American College of Rheumatology (ACR)/ European Alliance of Associations for Rheumatology (EULAR) classification criteria for Takayasu's arteritis (TAK) as compared to the 1990 ACR classification criteria in a Chinese population. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy and the area under the receiver operating characteristics curve (AUC) of the above two criteria were compared. The sensitivity (92.6%), positive predictive value (95.6%), negative predictive value (94.6%), accuracy (95.0%) and AUC (0.981) of the 2022 criteria were superior to those of the 1990 criteria (45.7%, 91.5%, 70.5%, 75.0% and 0.874, respectively), and the difference of AUC was statistically significant ( Z = 5.362, P
