Text: Several baseline characteristics predicted the operative risk of stroke and death in univariate analyses, but only four were independent risk factors in a multiple regression analysis : presentation with cerebral TIA vs ocular ischaemic events only (HR = 2. 99, 95 % CI = 1. 33-6. 69, p = 0. 008) ; female sex (HR = 2. 04, 95 % CI = 1. 37 -- 3. 06, p = 0. 001) ; systolic hypertension (HR = 1. 01 per 10 mmHg, 95 % CI = 1. 00-1. 02, p = 0. 03) and peripheral vascular disease (HR = 2. 17, 95 % CI = 1. 17-2. 89, p = 0. 001).
