Immunohistochemical analysis for omentin-1 in human adipose tissue. A representative slides of adipose tissue from patients in the CAD group (Fig. 3 A-a, EAT of non-stenosis subgroup; 3A-b, EAT of stenosis subgroup; 3A-c, SAT) and the NCAD group (Fig. 3 A-d, EAT; 3A-e, SAT) (magnified ×200). B results of quantitative immunohistochemical analysis for omentin-1 in EAT and SAT of the two groups (CAD group, n = 9; NCAD group, n = 9). C results of quantitative immunohistochemical analysis for omentin-1 in EAT of CAD group (total, n = 18; stenosis subgroup, n = 9; non- stenosis subgroup, n = 9) and NCAD group (n = 9). *P < 0.05, **P < 0.01.
