↵* Proportions were analyzed using Pearson chi-square tests; comparisons of continuous variables were performed with t tests.
↵a ENT includes jaw claudication, difficulty opening mouth, toothache, earache, tongue pain, sore throat, dry cough, and carotidodynia.
↵b Before 2003, relapse was defined as the recurrence of clinical symptoms or inflammatory variables that were attributable to GCA and required increased medication. Thereafter, only events involving clinical symptoms, or persistently raised acute-phase reactants with demonstration of new large-vessel involvement, were labeled as relapses.
↵c Patients free of relapse for at least 12 months following the cessation of GC treatment. aCL: anticardiolipin antibody; ACR: American College of Rheumatology; CRP: C-reactive protein; ENT: ear, nose, and throat; ESR: erythrocyte sedimentation rate; GC: glucocorticoid; GCA: giant cell arteritis; TAB: temporal artery biopsy.
