*number too low. SLE = systemic lupus erythematosus; SLEDAI (SLE disease activity index); SLIIC/ACR = Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index; RA = rheumatoid arthritis; DAS28-ESR = disease activity score 28 using erythrocyte sedimentation rate; HAQ = Health Assessment Questionnaire; SSc = Systemic sclerosis; Rodnan m = Rodnan modified; SpA = spondyloarthritis; BASDAI= Bath Ankylosing Spondylitis Disease Activity Index; BASFI= Bath Ankylosing Spondylitis Functional Index. SD = standard deviation; IQR = interquartile rate.
