Explanatory Variables of Enthesitis Resolution at 12-Month Follow-up (n=698). Logistic regression analysis for resolution of enthesitis based on multiple imputation of missing baseline covariate data. Analysis was performed with 698 treatment courses in patients who initiated TNFi and with available enthesitis assessments at 12-month follow-up. The numbers of enthesitis resolutions observed at 12-month follow-up was 300. All variables presented represent values at baseline. BMI is a categorical variable with levels defined as underweight (BMI <18.5), normal (BMI 18.5–24.9), and overweight (BMI >24.9). ASAS classification negative indicates patients not meeting ASAS criteria for axial spondyloarthritis. Predictors with 95% CIs that extend beyond the x-axis scale upper limit of 2 are indicated with an arrowhead at the end of the error bar. ASDAS-CRP, Ankylosing Spondylitis Disease Activity Score–C-reactive protein; ASAS, Assessment of SpondyloArthritis international Society; BMI, body mass index; mMASES, modified Maastricht ankylosing spondylitis enthesitisscore (modified to include the plantar fascia); TNFi, tumor necrosis factor inhibitor
