  • Values are median and IQR unless indicated otherwise, analysed by Mann-Whitney for non-normally distributed variables, t-test for normally distributed variables, χ2 for qualitative variables. p Values according to multivariate analysis of variance, adjusted for age, education level and disease duration (disease duration available only from Liverpool Hospital and Ridley Park).

  • *Disease duration not available.

  • MDHAQ, multidimensional health assessment questionnaire; OA, osteoarthritis; PATGL, patient global assessment; RA, rheumatoid arthritis; RADAI, rheumatoid arthrtitis disease activity index; RAPID3, routine assessment of patient index data 3.
