CCL14 and acute kidney injury: Hoste et al. found that urinary CCL14 was able to identify severe persistent AKI early [21], followed by external validation of CCL14 predicting persistent AKI in a study conducted by Sean M. Bagshaw et al.[22], which found that urinary CCL14 predicted persistent KIDGO stage 3 AKI with an Area Under Curve (AUC) was 0.81 [95% confidence interval (95% CI), 0.72–0.89], and the higher the urinary CCL14 value, the higher the risk of persistent KIDGO stage 3 AKI.
