Serum matrix metalloproteinase-3 (MMP-3) levels (a) and 7-joint ultrasound (US7) scores (b) in the different groups of patients with active rheumatoid arthritis (RA). a MMP-3 in patients with RA with moderate and severe disease activity were significantly higher than in patients with stable RA (105.10 vs 33.40, p < 0.001; 363.11 vs 33.40, p < 0.001). No significant differences were found between the group with mild RA and the group with stable RA or the normal control group (54.25 vs 33.40, p > 0.05; 54.25 vs 35.20, p > 0.05). b The US7 scores in patients with severe active RA were significantly higher than those in patients in the stable, mild, and moderate RA groups (7.8 vs 0.8 p < 0.001; 7.8 vs 2.2 p < 0.05; 7.8 vs 3.2 p < 0.05). No significant differences were found between patients with mild or moderate RA activity and those with stable activity (p > 0.05)
