  Yamaguchi and ILAR criteria
All suspected AOSD
 Kappa (p-value) 0.7144 (<  0.0001)
 95% confidence interval (0.5947, 0.8341)
AOSD-diagnosed patients
 Kappa (p-value) 0.3787 (< 0.0001)
 95% confidence interval (0.1416, 0.6159)
  1. The concordance between the Yamaguchi and ILAR criteria was assessed by the kappa (k) value: a k-value > 0.8 indicated excellent agreement, 0.61–0.8 meant good agreement, 0.21-0.4 indicated fair agreement, and < 0.2 was considered poor agreement
