Demographic characteristics are presented as mean (SD) or median (interquartile range). Statistical differences were determined using the Kruskal-Wallis test followed by Dunn’s Test.

Age and body mass index for Control and Living Donor groups were obtained at recruitment visit (RV).

*p < 0.05 compared to control.

p < 0.05 by paired analysis.

ADM = diabetes mellitus, PG = primary glomerulonephritis, SG = secondary glomerulonephritis, IN = interstitial nephritis, H = hypertension, CHC = cystic/hereditary/congenital, M = miscellaneous.

BRV measurements are at recruitment visit for Control and prior to kidney donation for Living Donor patients. 1YR measurements were obtained at 1 year follow-up. The arrows signify the separation of values obtained at RV and 1YR.

CMembrane surface area is presented as median (minimum to maximum).

Dp < 0.05 compared to conventional HD.

Ep < 0.05 compared to NIPD.

Fp < 0.05 compared to Home HD SHD.
