^†Number of discharge records among adults with diabetes mellitus in which AKI was a hospital diagnosis, End-stage renal disease was not a hospital diagnosis, and discharge status information was available. IQR= interquartile range. AKIN= Acute Kidney Injury Network criteria for definition of AKI.

^*Adjusted for age category, sex, CKD, sepsis, hypertension, hypotension, length of stay (LOS), acute myocardial infarction, congestive heart failure, chronic liver disease, computed tomography scan, angiography, admission source, payor source, race/payor interaction, hospital region, and hospital size.

^**After adjustment for age category, sex, CKD, sepsis, hypertension, hypotension, acute myocardial infarction, congestive heart failure, chronic liver disease, computed tomography scan, angiography, admission source, payor source, race/payor interaction, hospital region, and hospital size.
