Table 3: Encounter-adjusted Poisson regression of the recorded number of medications for depression by sex in patients with diagnoses of Parkinson disease and depression

Dependent variable*	Sex (male reference = 1.00)		No. of encounters with a primary care provider
Dependent variable*	RR (95% CI)	p value	RR (95% CI)	p value
No. of medications	1.08 (0.95-1.22)	0.2	1.11 (1.06-1.16)	< 0.001*

Note: 95% CI = confidence intervals (lower bound-upper bound), p value = probability value, RR = rate ratio.*Sex served as the main independent variable and number of encounters with a primary care provider in a 2-year period served as a covariate using a log-2 scale in the regression model.

†Significance defined as p < 0.05.
