Table 5.

Lack of association of age with changes in kidney function in donors and controls.

Measurement	Age (y)	Group	Rate of Change in Kidney Function	P^a
Measurement	Age (y)	Group	Rate of Change in Kidney Function	Donors vs Controls^b	Younger vs Older^c	Interaction^d
mGFR (mL/min per y)	< 45	Controls	0.08±9.46 (91)	0.007	0.9	0.2
	< 45	Donors	1.02±5.31 (89)
	≥ 45	Controls	−0.75±5.34 (103)
	≥ 45	Donors	1.83±4.77 (109)

Note: Values are given as mean ± standard deviation (number sampled). Abbreviation: mGFR, glomerular filtration rate measured by iohexol plasma clearance.

Analysis of variance.

Donors versus controls P values test differences between donors and controls.

Younger versus older P values test difference in age between younger (<45 years) and older (≥45 years).

Interaction P values test differences between donors versus controls and age.
