CST3 and chronic kidney disease: Multivariate logistic regression analysis showed that eGFR (OR = 0.979, 95% CI: 0.962–0.996, P = .017), cystatin C (OR = 2.123, 95% CI: 1.118–4.030, P = .021) and LMR (OR = 0.639, 95% CI: 0.421–0.969, P = .035) were still associated with high-grade ARAS in patients with CKD.
