Note: Based on 350 individuals with PD and 1050 matched controls without PD, aged 65 years or older and were alive during particular calendar year. Asterisks represent significant group differences by the presence of PD using t-tests. Ratio of means is computed as the ratio of expenditures for PD group divided by average expenditures of no PD group.
