Association of osteoprotegerin (OPG) levels with carotid occlusion outcomes. This figure illustrates the reduced risk of total or near-total occlusion in higher quartiles of OPG, especially in patients aged ≥ 60 years and those without coronary artery disease or previous myocardial infarction. The outcomes show a significant protective correlation (odds ratio < 1, P < 0.05).
