A rheumatologist independently evaluated laboratory findings, clinico-radiological data and other necessary examinations and re-assessed the CTD diagnoses. Patients were included in the IIM subgroup if they fulfilled either (I) the probable or definite European Alliance of Associations for Rheumatology/American College of Rheumatology (EULAR/ACR) Classification Criteria for Adult and Juvenile Idiopathic Inflammatory Myopathies and their Major Subgroups (2 (link)), or (II) the Connor’s criteria for ASyS (18 (link)). Other CTD diagnoses were confirmed by using the current International classification criteria of each disease (19 (link)-27 (link)). Eight patients with dry eyes, dry mouth, and Sjögren’s-syndrome-related antigen A/B (SSA/SSB) antibodies were included to SjS subgroup as highly probable SjS, without objective tests for dryness of mouth or eyes, but with multiple signs and symptoms supporting the diagnosis. Twenty-three patients with autoantibodies or clinical features of CTD without meeting the criteria for any specific autoimmune disease were included as UCTD (28 (link)).
