Description of the population studied and main results. The number of patients and controls with sufficient material used for the different analyses are shown in the graph. Seventeen parameters were investigated for association with the phenotype on the 81 patients (sex, age, disease duration, smoking status, HLA-B27, peripheral arthritis, enthesitis, uveitis, psoriasis, familial history of spondyloarthritis, radiographic sacro-iliitis, magnetic sacro-iliitis, CRP, BASDAI score, ASDAS, csDMARD intake, or NSAID intake). Differentially expressed miR expression were identified using a two-step process: Discovery in an exploratory cohort and confirmed in a replication cohort. MicroRNAs written in red are upregulated in the disease and those written in blue are downregulated in patients. A nominal p value < 0.05 was considered as significant
