Relationship between symptoms and change of JSW in subjects who had at least one progressed joint. A. JKOM score of the subjects who had progressed joints unilaterally (Uni) was compared with that of the subjects who had such joints bilaterally (Bi) at baseline and every 12 months. B. JKOM score of the subjects who had lower rates of JSW narrowing (<0.32 mm/year) (L) was compared with that of the subjects with higher rates of narrowing (≥0.32 mm/year) (H) at baseline and every 12 months. Higher JKOM score indicates severer symptoms. Results are mean + SD. *, P < 0.05, unpaired t-test.
