Multilevel linear regression models adjusted for patient age, education status, gender, number of chronic conditions, living situation, whether the patient is housebound or not, patient satisfaction with medications, the number of GP consultations in the 6 months prior to the study inclusion and the group allocation during the trial. Missingness: the change in the number of chronic medications over the 12 month follow-up period had 8% missing values. / *<0.05

*As calculated based on Reeve et al¹⁶ 2016.
