We defined periods of drug exposure based on pharmacy dispensing records and procedural administrations.
The MPR was determined based on pharmacy dispensing records, including the number of days supplied.
However, since these previous data were based on pharmacy dispensing records, which include prescriptions from GPs and psychiatrists, they may not adequately reflect GPs' role in prescribing psychotropic medication.
