Estimating the probability of stroke in Korean hypertensive patients visiting tertiary hospitals using a risk profile from the framingham study

Table 2 Average 10-year probability of stroke according to age in all subjects and blood pressure in treated hypertensive patients.

Age group	10 year risk of Stroke*	Stage of HTN	10 year risk of Stroke*
< 60 (n = 167)	12.42 ± 9.11^a	Normal (n = 134)	21.16 ± 17.23^a
60–69 (n = 654)	18.63 ± 13.89^b	Prehypertension (n = 535)	26.57 ± 18.92^b
70–79 (n = 467)	31.10 ± 20.42^c	Stage 1 HTN (302)	29.15 ± 19.48^b
> 79 (n = 114)	46.00 ± 23.15^d	Stage 2 HTN (95)	36.22 ± 23.74^c
P**	< 0.001	P**	<0.001

* Mean ± standard deviation
**P-value is for one-way analysis of variance
^a,b,c, same letters indicate statistical insignificance based on Duncan's multiple comparisons. Normal: SBP < 120 mm Hg and DBP < 80 mm Hg, pre-hypertension: 120 ≤ SBP < 140 mm Hg or 80 ≤ DBP < 90 mm Hg, stage 1: 140 ≤ SBP < 160 mm Hg or 90 ≤ DBP < 100 mm Hg, stage 2: SBP ≥ 160 or DBP ≥ 100 mm Hg.
