Scatter plot illustrating the relationship of UPCR (A) (n = 119) and UACR (B) (n = 146) with urinary vanin‐1, KIM‐1, and NGAL. Cr, creatinine; KIM‐1, kidney injury molecule‐1; NGAL, neutrophil gelatinase‐associated lipocalin; UACR, albumin‐to‐creatinine ratio; UPCR, urinary protein‐to‐creatinine ratio
