Freedom from hospital-acquired sepsis. Cox proportional hazards models showing the probability of remaining sepsis free for children with AKI versus no AKI after ICU admission. In these models, AKI was treated as a time-varying covariate with the value “0” assigned if the patient had not yet reached AKI onset; if the patient had met criteria for AKI, the value assigned was the highest KDIGO stage reached as of that time since ICU admission. (A) Probability according to AKI stage. (B) Probability according to any AKI stage. ICU, intensive care unit; KDIGO, Kidney Disease: Improving Global Outcomes.
