Relationship between the number of vascular risk factors and age groups.

VRF Number (n = 2054) n (%)	<55	55–80	>80	p-Value
1–2	130 (67.01)	591 (51.89)	439 (60.89)	<0.001
3–4	60 (30.93)	487 (42.76)	266 (36.89)
>4	4 (2.06)	61 (5.35)	16 (2.22)

VRF: vascular risk factor. Percentages are calculated based on the total for each age group (<55, 55–80, and >80 years). The chi-square test was used to evaluate the differences between <55 years old and 55–80, p < 0.001; <55 and >80, p = 0.180; 55–80 and >80, p < 0.001.
