Figure 2From: Reappraisal of the diagnostic and prognostic value of morning stiffness in arthralgia and early arthritis: results from the Groningen EARC, Leiden EARC, ESPOIR, Leiden EAC and REACHThe duration of morning stiffness per diagnosis in the Leiden EAC. The black horizontal line indicates the median duration. Number of patients per diagnosis after one year of follow-up: 2010-RA n = 1,140, SLE with peripheral arthritis n = 21, sarcoidosis n = 78, RS3PE n = 60, inflammatory arthritis n = 133, reactive arthritis n = 108, SpA/PsA with peripheral arthritis n = 287, crystal arthritis n = 119. Two data points (2010-RA n = 1 and SpA/PsA with peripheral arthritis n = 1) are outside the axis limits. EAC, Early Arthritis Clinic; PsA, psoriatic arthritis; RA, rheumatoid arthritis; RS3PE, remitting seronegative symmetrical synovitis with pitting edema; SLE, systemic lupus erythematosus; SpA, spondyloarthritis.Back to article page
