Data are expressed as the (range). The Mann–Whitney test was used to compare the age, and the chi-square test was used to compare sex between the two groups. BASDAI: Bath Ankylosing Spondylitis Disease Activity Index; BASFI: Bath Ankylosing Spondylitis Functional Index; CRP: C-reactive protein; ESR: erythrocyte sedimentation rate.
