Relationship between changes in renal function and clinical outcomes. Relationship between the absolute change in serum creatinine (A) and the percent change in eGFR (B) from baseline to 72 hours and the composite outcome death, rehospitalization, or emergency room visit within 60 days. The solid blue line represents a hazard ratio of 1. Histograms denote number of patients in each change in creatinine or eGFR group. CI, confidence interval; eGFR, estimated glomerular filtration rate; ER, emergency room.
