  1. Abbreviations: kg/m2 kilograms per meter squared, SD Standard Deviation. Diagnoses under “Others” include amyloidosis, HIV nephropathy, light chain tubulopathy, pyelonephritis, radiation induced kidney injury, thin basement membrane disease, thrombotic microangiopathy, microangiopathy likely due to bone marrow transplant, and non-specific renal changes. “Medication-Induced Renal Complications” were distinguished from “Interstitial Nephritis” in that a specific medication was a recognized as a cause for renal injury at the time of diagnosis. Medication-Induced Renal Complications included PPI induced allergic interstitial nephritis, NSAID induced CKD, and chemotherapy induced CKD
