Comparison of mature and immature OCN-expressing EPC levels in CAD vs non-CAD patients with or without dysbiosis revealed that immature OCN-expressing EPC levels were higher in CAD patients with dysbiosis than those in non-CAD patients without dysbiosis (P = 0.01), while there was no significant difference in mature OCN-expressing EPC levels among 4 groups (P = 0.55) (S1 and S2 Figs). This evidence concerns the gene BGLAP and coronary artery disorder.
