Figure 1: Flow chart of patients with IRD and CRP=5 mg/l and FiRST=5 (n=94). Splits are according to 1. previously known and newly diagnosed IRD, 2. therapy at the time of consultation/admission, 3. evaluation/disease activity/treatment. Among the remaining 14 patients (2.5% of all IRD), 7 (50%) had a concomitant FMS. IRD diagnoses among these 14 patients included undifferentiated connective tissue disease (CTD) (n=3), Sjögren’s syndrome (n=3), nr-axSpA (n=2), PsA (n=2), RA (n=1), panniculitis (n=1), suspected scleroderma (n=1), and Behcet’s disease (n=1). The disease was inactive or mild in 10/14 patients without major organ involvement.
