Table 4: Encounter-adjusted logistic regressions for the recorded type 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	OR (95% CI)	p value	OR (95% CI)	p value
Selective serotonin reuptake inhibitors	1.25 (0.90-1.73)	0.2	1.22 (1.08-1.39)	< 0.01*
Benzodiazepines and related hypnosedative	1.11 (0.80-1.54)	0.5	1.25 (1.10-1.42)	< 0.001*
Atypical and antipsychotic agents	1.12 (0.79-1.59)	0.5	1.10 (0.96-1.25)	0.2
Serotonin-norephinephrine reuptake inhibitors	1.18 (0.77-1.83)	0.4	1.06 (0.90-1.25)	0.5
Serotonin antagonist and reuptake inhibitors	0.64 (0.39-1.04)	0.07	1.14 (0.94-1.38)	0.2
Tricyclics and tetracyclics	1.73 (0.99-3.10)	0.06	1.32 (1.07-1.67)	0.01*
Bipolar medications	1.22 (0.69-2.16)	0.5	1.15 (0.93-1.43)	0.2
Monoamine oxidase inhibitors	0.76 (0.19-2.90)	0.7	1.23 (0.75-2.14)	0.4

Note: CI = confidence intervals, OR = odds ratio.

*Significance defined as p < 0.05.

Gender served as the main independent variable and the 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.
