EPS = encapsulating peritoneal sclerosis.
PET = peritoneal equilibration test.
PD = peritoneal dialysis.
D/P ratio Cr = dialysate-to-plasma concentration ratio for creatinine.
High defined as D/P ratio Cr >0.80, High average as D/P ratio Cr between 0.65 and 0.80, Low average as D/P ratio Cr between 0.55 and 0.64, and Low as D/P ratio Cr < 0.55.
The change of the PET exam between the first and the last PET exam from low to lower average, lower average to high average, or high average to high is defined as Delta 1; PET exam from low to high average or lower average to high defined as Delta 2.
