Values are presented as mean (range), number (%), or mean±standard deviation.

MRI: magnetic resonance imaging, RF: rheumatoid factor, CCP: cyclic citrullinated peptide, ANA: antinuclear antibodies, HLA: human leukocyte antigen.

*Statistically significant (p<0.05). Stiffness: decrease of passive ankle dorsiflexion range compared to normal side ≥5°.
