  • * Erythrocyte sedimentation rate (ESR) and anxiety are logarithmically transformed.

  • Statistics of the final models are shown.

  • Time consists of 11 time points, numbered 0–10, measured at baseline and every 6 months up to 5 years.

  • § Depressed mood 0/1 is a dichotomous variable with 0 for zero scores and 1 for scores exceeding zero.

  • RF, rheumatoid factor.
