Factors influencing the probability of the correct inclusion of an acute aortic dissection in the first differential diagnosis

	RR	(95% CI)	P
Female sex	0.66	0.44–0.99	0.04
Age	0.99	0.98–1.01	0.55
Extracardiac atherosclerosis	0.64	0.43–0.96	0.03
Connective tissue disease	3.17	0.49–20.7	0.23
Absence of back pain	0.51	0.30–0.84	0.008
Migratory pain	1.37	0.42–4.39	0.60

Table shows the multivariable-adjusted relative risk (RR) for the correct inclusion of an aortic dissection in the first differential diagnosis. An RR > 1 indicates that a correct suspicion of an AD is more likely, while an RR < 1 indicates a lower likelihood for the mentioning of an AD
