“…Through ROC analysis, we uncovered that serum CDC42 > 1.025 was conducive to differentiating uremia patients with VC from uremia patients without VC (AUC: 0.7374, sensitivity: 83.58%, specificity: 56.76%), and serum CDC42 > 1.280 was effective in the diagnosis of VC progression (AUC: 0.7004, sensitivity: 73.33%, specificity: 68.18%). Compared with previously validated biomarkers, such as miR-211-5p (AUC: 0.889, sensitivity: 81.2%, specificity: 84.4%) [ 38 ] and osteoprotegerin (AUC: 0.79, sensitivity: 91.7%, specificity: 59.0%) [ 39 ], CDC42, though does not outperform in the prediction of CKD-related VC, has additional capacity to predict whether the severity of VC may be increased in the following 2 years. Moreover, CDC42 was evidenced as an independent risk factor for VC incidence ( P = 0.011, OR = 4.427, 95%CI = 1.401–13.986) and progression ( P = 0.003, OR = 4.703, 95%CI = 1.694–13.059).…”
