Ankle Blood Pressure and Pulse Pressure as Predictors of Cerebrovascular Morbidity and Mortality in a Prospective Follow-Up Study

Table 2

Hazard ratios (HR, 95% Confidence Interval (CI)) of cerebrovascular events according to the specified blood pressure groups (total 𝑛=3808, no of events = 170).

Blood pressure group	Model 1			Model 2
	HR	95% (CI)	𝑃 values	HR	95% CI	𝑃 values
Group I	1	(Reference)		1	(Reference)
Group II	2.69	1.78–4.07	<.0001	2.24	1.43–3.52	<.0001
Group III	2.60	1.60–4.20	<.0001	2.09	1.21–3.61	.008
Group IV	2.71	1.44–5.10	.002	2.37	1.31–4.69	.007
Group V	7.82	4.67–13.12	<.0001	5.78	3.31–10.10	<.0001

Model 1: adjusted for age and sex.
Model 2: adjusted for age, sex, BMI, resting brachial systolic blood pressure, smoking, early parental cardiovascular disease and physical working capacity (METs), self-reported elevated cholesterol, and abnormal blood glucose.
Please see Section 2 for the explanation for the blood pressure groups.
