^*In most cases, the etiology of AKI was multifactorial, so the categories are not mutually exclusive. This is why the percentages add to above 100%, and why separate p-values were calculated for each category.

^†Other consists of nephrotoxin induced, rhabdomyolysis-induced, malignancy associated, and unknown etiology.
