  • Values are presented as percentages, median (interquartile range), or mean (SD). For time on dialysis median and interquartile range are presented. AD is a subtype of dementia; therefore, the AD cases are a subset of the dementia cases. Dementia and AD are ICD-reported diagnoses of dementia or AD. GED, General Educational Development test; PRA, panel reactive antibody; HLA, human leukocyte antigen; CIT, cold ischemia time.
