Scores for synovitis detected by magnetic resonance imaging (a) and tenosynovitis (b) in patients with early arthritis (n = 589) with different combinations of anti-citrullinated protein antibodies (ACPA), rheumatoid factor (RF) and anti-carbamylated protein antibodies (anti-CarP). Horizontal lines represent median. Whiskers show the 10th–90th percentile. Dots represent outliers. Synovitis: ACPA+, RF+, anti-CarP+ patients vs. ACPA-, RF-, anti-CarP- patients, p < 0.001. Tenosynovitis: ACPA+, RF+, anti-CarP+ patients vs. ACPA-, RF-, anti-CarP- patients, p < 0.001; ACPA+, RF+, anti-CarP+ patients vs. ACPA+, RF+, anti-CarP- patients, p = 0.039. ACPA-, RF-, anti-CarP- patients, n = 353; ACPA-, RF+, anti-CarP- patients, n = 69; ACPA+, RF-, anti-CarP- patients, n = 15; ACPA+, RF+, anti-CarP- patients, n = 48; ACPA-, RF-, anti-CarP+ patients, n = 11; ACPA-, RF+, anti-CarP+ patients, n = 3; ACPA+, RF-, anti-CarP+ patients, n = 5; ACPA+, RF+, anti-CarP+ patients, n = 69. Total score: sum of scores in metacarpophalangeal, wrist, and metatarsophalangeal joints. *Significant difference between subgroups (p < 0.05)
