FRAX: fracture risk assessment tool; DAS28: Disease Activity Score for 28 joints; HAQ-DI: Health Assessment Questionnaire Disability Index; ESR: erythrocyte sedimentation rate; ACPAs: antibodies against cyclic-citrullinated peptides/proteins included anti-CCP2 or anti-MCV; sRANKL: Soluble Receptor Activator for Nuclear Factor kappa B Ligand; OPG: osteoprotegerin; DKK-1: Dickkopf-1; SOST: sclerostin; OC: osteocalcin; CTSK: cathepsin k. Correlations between biomarker serum levels and FRAX indices were performed using Pearson test.
