DMARD = disease-modifying antirheumatic drug; MTX = methotrexate; SSZ = sulphasalazine; HCQ = hydroxychloroquine; TNFα = tumour necrosing factor α blockade; BMI = body mass index; DAS28 = disease activity score using 28 joint counts; LFISIF = Leeds Foot Impact Scale-Impairment/Footwear subscale score 9 range 0–21); LFISAP = Leeds Foot Impact Scale-Activity Limitation/Participation Restriction subscale score (range 0–30); SJC = swollen joint count (range 0–14); TJC = tender joint count (range 0–14); PJC = painful joint count (range 0–14); SIFF = structural index for forefoot; SIRF = structural index for rearfoot. RSFP = relaxed standing foot posture.
