Association between diagnosis of polymyalgia rheumatica and all vascular events, by sex and age

Characteristic	All vascular events, rate per 1000 person-years (95% CI)		Hazard ratio (95% CI)
	PMR	No PMR	Unadjusted	Adjusted*
Sex
Male	43.7 (38.9–49.3)	15.7 (14.3–17.3)	2.8 (2.4–3.2)	2.5 (2.1–2.9)
Female	33.5 (30.9–36.2)	11.0 (10.3–11.8)	3.1 (2.7–3.3)	2.7 (2.4–2.9)†
Age, yr
50–59	19.5 (15.1–25.0)	3.5 (2.6–4.6)	5.6 (3.8–8.1)	5.0 (3.4–7.4)

Note: CI = confidence interval, PMR = polymyalgia rheumatia.

^*Adjusted for age, sex, ever having smoked, and record of hypertension, hyperlipidemia, diabetes or giant cell arteritis. Models stratified by age were adjusted only for sex, and vice versa.

^†Assuming separate baseline hazards for those with and without diabetes mellitus.
