Extreme Elevations in Blood Pressure and All-Cause Mortality in a Referred CKD Population: Results from the CRISIS Study

Table 3

Hazard ratio for death for patients with extreme hypertension at baseline.

	12-month mortality		Overall mortality
	Hazard ratio (95% confidence interval)	𝑃	Hazard ratio (95% confidence interval)	𝑃
Resolved by one year (𝑛=55)	Referent		Referent
Extreme hypertension persisting at one year (𝑛=9)	2.7 (0.5–13.7)	0.2	3.47 (1.1–11.1)	0.03
Age	1.06 (1.02–1.09)	0.002	1.05 (1.02–1.1)	0.05
Estimated glomerular filtration rate (mL/min/1.73 m^2)	0.98 (0.96–1.01)	0.2	Not retained
Hemoglobin (g/dL)	Not retained		0.96 (0.93–0.99)	0.05
Smoking history	Not retained		2.4 (0.8–7.4)	0.1
Diabetes mellitus	1.67 (0.7–3.9)	0.1	Not retained

Data are presented as hazard ratio (95% confidence interval). Results for continuous variables are presented per 1 unit increment. Smoking history defined as current or previous smoking.
