Osteopontin and Osteoprotegerin as Potential Biomarkers in Abdominal Aortic Aneurysm before and after Treatment

Table 2

Serum OPN and OPG correlations of AAA patients (overall, aortic, and aortoiliac aneurysm groups) versus the control group and OR versus EVAR group. All mean values are given with standard deviation (SD).

	AAA patients			Control group; (𝑛=20)
	Overall (𝑛=74)	Aortic (𝑛=54)	Aortoiliac (𝑛=20)
OPN (mean value ± SD, ng/mL)	3661.64 ± 1126.49 (𝑃=0.017)	3878.30 ± 1381.69 (𝑃=0.03)	3076.68 ± 1778.5 (𝑃=0.01)	1418.30 ± 962.68
OPG (mean value ± SD, ng/mL)	354.28 ± 212.1 (NS)	330.69 ± 187.45 (NS)	417.97 ± 262.64 (NS)	364.87 ± 159.85
	OR; (𝑛=34)		EVAR; (𝑛=40)	𝑃
OPN (mean value ± SD, ng/mL)	2194.15 ± 800.24		4909.01 ± 2574.6	NS
OPG (mean value ± SD, ng/mL)	320.96 ± 206.6		382.6 ± 215.17	NS

AAA: aortic abdominal aneurysm; OR: open repair; EVAR: endovascular aneurysm repair; OPN: osteopontin; OPG: osteoprotegerin.
