  1. Data presented as median (interquartile range) or number (%). Sepsis-shock-associated acute kidney injury (SSAKI) defined as a persistent >200% increase of serum creatinine at day 7 of hospitalization. aTwenty-eight-day mortality. bRefers to patients in which no pathogenic organism was isolated. The total percentage of organisms does not add up to 100% because patients with either a fungal or viral pathogen were not included. *P <0.05 versus patients without kidney injury.
