  1. Coef. coefficients in the logistic regression, Std.Err. standard error in the coefficients, VAS visual analogue scale, ESR erythrocyte sedimentation rate for an increase in 10 mm/h, CRP C-reactive protein, ANA antinuclear antibody, HLA-B27 human leucocyte antigen
  2. aNot in remission equals non-achievement of remission off medication
