CCL14 and Sepsis: We also performed a subgroup analysis to further investigate the diagnostic value of CCL14 in sepsis-associated persistent severe AKI, and the results suggested that CCL14 could predict persistent severe S-AKI at T0, but not after 6 h of ICU admission, which may be related to the decay of the marker, further studies are needed to explore the change pattern of CCL14 over time.
