Figure 1. Sequential musculoskeletal ultrasound (MSUS) at baseline and after 4 months of follow-up in arthralgia patients at risk for inflammatory arthritis (IA):
(A) patients with subclinical inflammation at baseline; (B) patients without subclinical inflammation at baseline. *Percentage IA development is calculated based on the group at baseline (n = 25 for MSUS+ and n = 27 for MSUS−). In total, 15 patients developed IA within 1 year (n = 10 baseline MSUS+, n = 5 baseline MSUS−).
