Lung cancer*	10 (50.0)*	11 (36.7)*	4 (14.3)*	0.11†
Cardiac-/cerebrovascular events	6 (12.2)	14 (21.9)	10 (17.2)	0.41†
COPD	5 (10.2)	3 (4.7)	1 (1.7)	0.16‡

Other	6 (12.2)	6 (9.4)	5 (8.6)	0.85‡
Missing data	3 (6.1)	5 (7.8)	5 (8.6)	0.94‡

Notes: Column headings are stated in bold text. Data are presented as n (%). P-values were calculated using Pearson’s Chi-squared test^† or Fisher’s exact test^‡. *Cases of lung cancer (italicized text) are noted as a separate subgroup under malignant disease, with the percentages given relative to the total number of participants who died from malignant disease in each of the three aortic diameter groups.

Abbreviation: COPD, chronic obstructive pulmonary disease.
