Pearson's correlation coefficients among the tubular damage biomarkers and main renal parameters
| Characteristic | eGFR | L‐FABP | uKIM‐1 | sKIM‐1 |
|---|---|---|---|---|
| ACR | −0.26* | 0.67* | 0.28* | 0.51* |
| eGFR | – | −0.31* | −0.10** | −0.37* |
| L‐FABP | – | – | 0.16* | 0.41* |
| uKIM‐1 | – | – | – | 0.43* |
*P < 0.0001, **P < 0.05. ACR, urinary albumin‐to‐creatinine ratio; eGFR, estimated glomerular filtration rate; KIM‐1, kidney injury molecule‐1; L‐FABP, liver‐type fatty acid‐binding protein. The s and u prefixes denote serum and urinary sources, respectively.
