From: The outcome of acute kidney injury substages based on urinary cystatin C in critically ill children
Forest plot depicting the risk of 30-day PICU mortality. The non-AKI with the lowest risk of mortality was used as a reference. Adjusted HR: Model was adjusted for body weight, sex, illness severity assessed by the pediatric risk of mortality III score, multi-organ dysfunction syndrome, and mechanical ventilation. KI, acute kidney injury; CI, confidence interval; HR, hazard ratio; NA, not applicable; PICU, pediatric intensive care unit; sub-AKI, subclinical AKI; uCr, urinary creatinine; uCysC, urinary cystatin C
