ACEI, angiotensin-converting enzyme inhibitor; ARB, angiotensin II receptor type 1 blocker; BBB, blood-brain barrier; cDDD, cumulative defined daily dose; CI, confidence.iInterval; DDD, defined daily dose; HR, hazard ratio.
The number of subjects in each category of drug type is not mutually exclusive, as the definition of each number of subjects was based on the population who used that drug at least once.
The incidence rate is presented per 1,000 person-years.
Adjusted for all covariates presented in Table 2 with a multivariate Cox proportional hazard model for Parkinson’s disease.
