ALB and type 2 diabetes mellitus: Binary logistic regression identified independent risk factors for advanced CKM in early-onset T2DM: urine albumin-to-creatinine ratio (UACR; OR = 1.077, 95% CI: 1.046–1.110), blood urea nitrogen (BUN; OR = 1.202, 95% CI: 1.005–1.436), and diabetes duration (OR = 1.102, 95% CI: 1.060–1.145).
