a
End-Stage Renal Disease
b
Chronic Kidney Disease
c
Kidney Transplant
d
Based on Taylor-linearized estimation comparing different populations (ESRD vs. CKD vs. TXP or Formal Transition vs. No Formal Transition)
e
Unclear primary source of insurance coverage during period of review related to limited availability of old administrative records
f
NS compared to ESRD
g
p=0.018 compared to ESRD
ESRD – end stage renal disease; CKD – chronic kidney disease; TXP – kidney transplant
