title: [A comparative study of diagnostic efficacy of different diagnostic/ classification criteria in Takayasu arteritis].
abstract: OBJECTIVE
  This study aimed to analyze and evaluate the diagnostic efficacy of Ishikawa's, the modified Ishikawa's criteria, 1990 American College of Rheumatology (ACR ) classification criteria and the diagnostic model based on Chinese population in Chinese TA patients.
  
  
  METHODS
  One hundred and forty-nine patients with Takayasu arteritis and 126 patients with other vascular disorders which involved aorta or its branches were recruited in this study.All the patients were admitted to the Department of rheumatism and Immunology clinic or inpatient department of Zhongshan Hospital affiliated to Fudan University from January 1(st), 2008 to June 31(st), 2015.General characteristics, clinical manifestations, laboratory results and imaging data of all the patients were collected.Sensitivity, specificity, accuracy and area under receiver operating characteristics (ROC) curve of different criteria were analyzed.
  
  
  RESULTS
  Sensitivity, specificity, accuracy and area under ROC curve of Chinese diagnostic model were 90.60%, 80.95%, 86.18%, and 85.80%, respectively, while those of Ishikawa criteria were 34.23%, 99.21%, 64.00%, and 66.70%, respectively.These four indicators of the modified Ishikawa criteria were 84.13%, 79.87%, 81.82%, and 82.00%, respectively and that of ACR criteria were 83.89%, 83.33%, 83.64%, and 83.60%, respectively.No significant difference was found between any two of Chinese diagnostic model, the modified Ishikawa criteria and ACR criteria in all the indicators.Sensitivity of Chinese diagnostic model was highest, while specificity of Ishikawa criteria was the highest.Among these four criteria, the diagnostic efficacy of Chinese model was the best and that of Ishikawa criteria was the worst.
  
  
  CONCLUSIONS
  Chinese diagnostic model, which is based on Chinese population and adopts advanced imaging modality, has better diagnostic efficacy.
