Females were less likely to be prescribed a PD-related medication (8%, 95% CI = 6–11 of females not taking a PD medication, compared to 5%, 95% CI = 4–6 of males, exact p = 0.006, corrected p = 0.030), while males were prescribed acetylcholinesterase inhibitors more frequently than females (12%, 95% CI = 10–14 versus 5%, 95% CI = 4–7, respectively, exact p = 0.000006, corrected p = 0.00006). The gene discussed is ACHE; the disease is Parkinson disease.
