Predictors for pathologically confirmed aortitis after resection of the ascending aorta: A 12-year Danish nationwide population-based cross-sectional study

Table 1 Main indications for surgery of the ascending aorta in 1,210 patients

Variable^a	With pathological examination of aorta				Without pathological examination of aorta, n= 600 (%)
	Without aortitis, n= 573 (%)	With aortitis, n= 37 (%)	OR for aortitis (95% CI)	P
Aneurysm^b	469 (82)	30 (81.1)	1.3 (0.5-3.3)	0.53	423 (81.8)
Pathology of the aortic valve^c	261 (45.6)	24 (64.9)	2.3 (1.1-4.9)	0.027	279 (46.6)
Malformation^d	21 (3.7)	1 (2.7)	0.7 (0.1-5.2)	0.69	19 (3.2)
Infection	8 (1.4)	1 (2.7)	1.7 (0.2-14.9)	0.61	30 (5)

Patients with and without pathological examination and with and without a diagnosis of aortitis, Denmark, 1997 to 2009 (logistic regression analysis, adjusted prevalence ORs for aortitis).
CI, confidence interval; OR, odds ratio.
^a Several conditions/indications could be present for the same patient.
^b With or without dissection.
^c Refers to aortic valve functional status, i.e. insufficiency, stenosis.
^d Refers to anatomic information, i.e., bicuspid valve, other congenital malformation.
