  • Results were from linear regression model of standardised change.

  • *This analysis included participants who completed the outcome questionnaire (EQ-5D-5L or PACIC) and the MTBQ questionnaire at baseline and 9-month follow-up.

  • †Linear regression model further adjusted for age, gender, number of comorbidities, age left full-time education and individual deprivation score.

  • ‡This analysis included participants who completed the outcome questionnaire (EuroQol five dimensions, five level questionnaire (EQ-5D-5L), PACIC or MTBQ) at baseline and 9-month follow-up.

  • MTBQ, Multimorbidity Treatment Burden Questionnaire; PACIC, Patient Assessment of Chronic Illness Care.
