	Cases (n = 542), no. (%)	Controls (n = 2,155), no. (%)	Crude OR (95% CI)	Adjusted OR (95% CI)
No dopamine agonist use	366 (67.5)	1,516 (70.3)	1.0 (Ref)	1.0 (Ref)
Dopamine agonist use	176 (32.5)	639 (29.7)	1.16 (0.94–1.43)	1.19 (0.95–1.49)
Ergot use	103(19.0)	381 (17.7)	1.13 (0.88–1.46)	1.22 (0.93–1.60)
Nonergot use	73 (13.5)	258 (12.0)	1.20 (0.89–1.62)	1.15 (0.83–1.57)

Adjusted for use of drugs to treat cardiovascular disease and prior hospitalization 1 year before the index date and for prior hospitalization due to ischemic event before November 1997
