a
Due to missing values on covariates, the number of included GPs are reduced from 1676 to 1664 in the full model.
b
Data missing for 12 GPs.
c
Omitted owing to multicollinearity with multimorbidity.
d
Omitted as rate of patients with multimorbidity is sex- and age-standardised. CI = confidence interval. DADI = Danish Deprivation Index. OR = odds ratio.
