EULAR/American College of Rheumatology (ACR) classification criteria for paediatric chronic nonbacterial osteomyelitis (CNO)
Authors' conclusion
These new classification criteria for paediatric CNO developed with international input reflect current views about CNO, have high specificity and good sensitivity, and provide a key foundation for future CNO research.
