Note: The category “acute systemic disorders” was not incorporated because of small numbers (n = 3). p-Values represent the difference between young stroke patients aged <35 years versus ≥35 years or sex, respectively. RF: risk factor.
a
Vascular imaging (MRA/CTA/conventional angiography) not performed in n = 288 (excluding duplex of carotid arteries).
b
Women, n = 347
