The relationship between serum OCN and vascular function in patients with chronic kidney disease (CKD) is uncertain. This study investigated the association between serum OCN and vascular function as expressed with reactive hyperemia index (RHI) and augmentation index (AIx) measured by Endo\u2010PAT 2000 device. This cross\u2010sectional analysis was based on 256 pre\u2010dialysis CKD patients who had completed the Endo\u2010PAT 2000 test and serum OCN at the First Center of Chinese PLA Hospital from November 2017 to December 2019. Based on whether the RHI was less than 1.67, the patients were divided into endothelial dysfunction and normal endothelial function groups. Multiple logistic and linear regression were used to analyze the association between OCN and vascular function. Subgroup analyses were performed to examine the effects of OCN on vascular function in different CKD populations. After multivariate adjustment, CKD with low OCN were more likely to have endothelial dysfunction (OR: 0.794; 95%CI: 0.674\u20100.934;\n                    <jats:italic>P<\/jats:italic>\n                    \u00a0=\u00a0.006); on the contrary, patients with high OCN had a higher degree of arterial stiffness (standardized\n                    <jats:italic>\u03b2<\/jats:italic>\n                    : 0.174;\n                    <jats:italic>P<\/jats:italic>\n                    \u00a0=\u00a0.003).
