legend: a Each row header indicates the specific MSK in which the strata-specific association between multimorbidity and each burden measure has been estimated. For each row, the reference group is those with the specific MSK but not multimorbidity. Associations (odds ratios) are adjusted for age, gender, SES, education, smoking and medium to high risk alcohol consumption. All general healthcare utilisation measures relate to the 12 months prior to the interview. bEach interaction p-value indicates whether the association between multimorbidity and the burden measure differs between the specific MSK group and the remaining MSK population. Significant (p < 0.05) interactions are bolded and further details are presented textually in results section
