The Estimation Formula for the Urinary Albumin-Creatinine Ratio Based on the Protein-Creatinine Ratio Are Not Valid for a Kidney Transplant and a Living Donor Cohort

Weaver et al. [1][1] recently described equations for estimating the median urinary albumin-to-creatinine ratio (ACR) from the protein-to-creatinine ratio (PCR) on the basis of median regression models for log ACR in a Canadian population–based cohort. Patients with kidney transplants (KTx) were
