Effect of aneurysm neck length on 30‐day mortality, by treatment commenced. The analysis was restricted to patients with ruptured abdominal aortic aneurysm who underwent CT, commenced treatment and did not have a common iliac aneurysm. All analyses were adjusted for age, sex, Hardman index, admission mean arterial BP, treatment commenced and randomized group. Multiple imputation was used to account for missing data. Odds ratios of 30‐day mortality per 15‐mm increase in aneurysm neck length are shown with 95 per cent c.i. EVAR, endovascular aneurysm repair
