Different options for defining and reporting AKI outcomes. Illustration of how different theoretical options in serum creatinine (level A, five variants) and urine output (level B, four variants) could lead to twenty different ways of assigning a KDIGO stage per observation day. Here, eight practical combinations of A and B are shown. In total, this results in a total of 32 variations of reporting AKI, as AKI can be expressed for example using one of the four displayed reporting outcomes. However, defining AKI on both sCr and UO cannot be done for the two practical combinations in which either sCr or UO is used. Hence, 30 different variations were investigated. AKI, acute kidney injury; sCr, serum creatinine; UO, urine output; MDRD, Modification of Diet in Renal Disease; CKD-EPI, Chronic Kidney Disease Epidemiology Collaboration
